How big of a difference will there be if I change my catalytic converter to a test pipe?

I have high performance catback and headers installed but I have the stock catalytic converter connecting them, it sounds really good right now but will there be any performance gains, like how much horsepower would be gained from a test pipe and also will it change the sound because I love the sound, it is really deep and not too loud.|||The main thing you will notice is that no reputable shop will do it, and if you can find a shop that will, you will probably need to tow it there on a trailer, pay cash and trailer it away. You then can expect to never have any reputable shop anywhere ever work on it again until you put a cat on. If you take it to the right shop, they will call the EPA, and they will give you a $2,500 fine for removing it, and give the shop that did it a $10,000 fine.





But in a hypothetical situation, you will lose HP and torque by removing it. Modern engines need a certain amount of back pressure to ensure proper scavenging. This back pressure is created by the cat, and most modern cats produce very little back pressure. If you have no cat, your vehicle will blow unburnt fuel out your exhaust, will burn exhaust valves, and smell like @$$ to any poor soul behind you. Very uncool in my book......|||There would be a modest gain (maybe one horse). Most modern catalytic converters are pretty free flowing. They are required by law and to remove one is a irresponsible act.


Now if you want better performance, just get some better headers and maybe a mega-flow catalytic. That is what I did.

Is it legal to sell a car without a catalytic converter on it in Ohio?

I bought a blazer 2 weeks ago, when I got it home the "check engin" light came on. When I took it to get looked at I was told there was no catalytic converter on it.|||Yes, it's legal.





It is the buyer's responsibility to have the car checked out by a mechanic before the car's purchased. All used vehicle sales via private party are "as is" unless noted in writing.|||Was it sold As is? If so yes.|||It is very legal to buy a vehicle without a cat converter. Heck, you just did it!

What happens if they catch me with out a catalytic converter?

I live in Chicago ill and I have a 1996 Honda Accord and I removed my catalytic converter and was wondering if i will pass the emission test because i dont have the check engine light on and if they catch me without one what will they do?|||A year ago it might be no big deal. This year or next you can bet it will be a big deal indeed. Besides Illinois fines the EPA will want a bite of you, and the last I heard they want $25K for an unauthorized change to a vehicle emission system. Don't worry about jail - that is just there to make sure you pay the fine no matter how many years it takes you to pay it off.





In the past year every regulatory agency I deal with at work - US Forest Service, FCC, OSHA, EPA, Highway Patrol - has stepped up enforcement and all are quite candid that it is to collect fees and fines at every possible opportunity. The EPA knows there are enough illegally modified vehicles out there to ease their budget problems and you can bet there are going to be lots of surprise inspections coming Real Soon Now. They would be incredibly stupid not to, and they are not incredibly stupid.|||its Not a " $10,000 " Nor Would you Get 2 years in the pin Thats Just Crap.. i use to run my 74 Nova With open headers at best you would get a Ticket for excessive noise and have to have it fixed by law you Should have one as Well as Mufflerer but in this Day and age cops dont Really make a big deal out of that unless its REALLY Loud..and No it Would Not pass an emission test Seeing how thats What the catalytic converter if for.. i would Call your local Police Department or DMV And Make Sure as Far as What the Fine would be i Hope this Helpd you|||Champ is right. The fine is hefty. I have seen some people keep the converter housing and run a straight piece of pipe through it. Either way, it's very risky and can cost you more in the end.|||You will likely not pass your admissions test, and will likely to be forced to replace the CC.|||No you will not. Illinois does the engine light test AND the dyno emission test. If they find you don't have a cat on your car, they will not pass you.|||$10,000 fine and without it you WON'T pass an emissions test guaranteed.|||The last time I checked it was a $10,000 fine and up to 2 years in prison.

Also my car switches gears kind of rough would the catalytic be the problem of that too? So what do you guys think is it time for a new catalytic converter or not? Thanks.|||You shouldn't replace your converter unless it has gone completely bad. You will know this by hearing rattling from under your car, and a smell of rotten eggs whenever the engine is warm and running.





And no, the converter is in no way affiliated with the transmission. It is not causing your rough gear switching. That would require new transmission fluid.|||Go to the tail pipe and feel the exhaust.It should be good pressure-it should push your hand away-if not it may be time for a new unit-also are you smelling a rotten egg smell??a good indicator of a bad cat-if you hit the cat with your hand(COLD EXHAUST) does it rattle???Cat is broken up inside %26amp; needs a new one.Now--2nd part--Have you had a transmission service done lately???Transmission service cures most poor shifting in 90 out of 100 cars I work on-some need more help ,but try a service first-a good tranny guy can look at the contents in the pan %26amp; tell you whats going on.|||There is a chance that it is the catalytic converter but really can't say 100%.

Could the catalytic converter being broken cause the air bag light to go on?

In December I hit a block of ice and broke the catalytic converter in my Jetta. About 20 minutes after this happened the airbag light went on and has not gone off since. When we got the car checked out to see what was wrong with it we were sent to a muffler shop to replace the cat con and they had no explanation for the air bag light. Could it be related? My husband says no but it seems like to much of a coincidence that they happened at the same time.|||What happened is when you hit the cat you damaged the wiring for the sensor for the air bag.

What does it mean to straight pipe a catalytic converter?

i have a 96 toyota 4runner and there's something wrong with the catalytic converter. someone told me i should just straight pipe it. what exactly does that mean? what does it consist of? what will it do to my car, and how easy or hard is it to have someone do it at home?|||Whoever told you does not know jack. Is illegal and the vehicle was not tuned from factory that way. As stated before... it will run like crap. Just put one back on. There are some good aftermarket Cats that will increase Exhaust Flow and give you few Ft/Lb of Torque and few HPs more. But they cost more and the gain is not that great.





1st what is doing now that you need to change the Cat? If is running really bad, it will get worst. As simple as that ! And if is fine, why do you want to change/remove it?|||In Arkansas they could care less if you take it off, not illegal here.

Report Abuse

|||It's a $10,000. Federal fine if you get caught.|||What they want you to do is take the converter off and replace it with a piece of exhaust pipe. It will have no effect on your engine except that it will breath easier (less back pressure).The down is that in most states, (if not all) it is illegal to do this. There are some muffler shops that will do it for you if you check around. Anyone who has done exhaust work at home in their garage can probably handle the job.|||what they said....|||It means to remove the catalytic converter and replace it with a piece of exhaust pipe. On your year of vehicle the check engine light will stay on and your gas mileage will go down.|||It's not that expensive to replace the cat convertor and it'll keep you legal. Your not likely to get a check engine light unless you have an O2 sensor (oxygen sensor) mounted past the cat convertor.





Straight piping is only allowed if you ship the car outside the country to a place that still sells only leaded gasoline.





Otherwise, the penalty costs exceed the replacement costs so a new cat convertor is cheapest in the long run. You can ask your local parts retailiers how much one costs for you car and then find someone to install it for you. Labor is only like 1/2 hour and the part is probably less than $200 for a small car like yours.





I replaced my own cat convertor on my 1985 truck six years ago and it cost me only $110.





Good Luck!|||to put a PIPE in the place of your Cat. Converter. It's Illegal. Except for racing on tracks and such..

My car has the original 24 year old Catalytic Converter on the car. Is there anyway it could still be good?

It's always been a summer car so seen no winter, and has under 60,000miles/100,000km on it.





Is there anyway that the Catalytic Converter could still be good after 24 years?|||It probably is, catalytic converters wear out when all the chemical elements inside them are gone from reacting with the exhaust, this usually takes a long time. The most common way that they go bad is from getting clogged, so if there is still exhaust coming out of your tailpipe then it is most likely still good.|||No reason to doubt the catalyst. They are supposed (supposed I might add), to last the life of the vehicle.

Is a VW catalytic converter covered under Exhaust Emission Warranty?

My catalytic converter is fine, BUT the pipe is defective. It's all one piece, so the whole thing needed replacing. Is the pipe considered part of the converter and therefore covered under warranty? My car is less than 8 yrs / 80,000 miles.|||yea it should be call a dealer to make sure, it may be cheaper for them to fix it all in one, then cutting out what they need|||Catalytic converters are federally mandated to be warrantied for 100,000 miles, the pipes are not. In order for the cat to be covered the vehicle has to be experiencing driveabiltiy problems due to its failure, or, the car must fail an emissions test, also specifically due to its malfunction. These were the rules when I was working on cars. If it is just a pipe, some can be repaired or spliced, welded or patched. You need to find a reputable technician whom you trust, or better yet, that you know to look at it before you do anything else.

Got new diesel exhaust with no catalytic converter: Is it much worse for the environment?

I've got a 2006 Silverado 2500HD with the Duramax 6.6L diesel. I recently upgraded to a turbo-back exhaust system, which apparently has no catalytic converter. Where I am this is legal, but I know the converters are there for a reason. How much of a difference do they really make? Should I feel really guilty about destroying the environment and switch back to stock exhaust?|||If you are concerned about the environment you wouldn't be driving a truck anyways, or a diesel one at that. Don't worry about it, because that exhaust probably made your truck more fuel efficient. Burning less fuel is the best way to reduce emissions.|||Diesels don't ever have catalytic converters thats why they are more fuel efficient. diesels engines are made to produce more torque at slower rpms the cat converter makes that hard to do. The converter uses energy from the engine to heat exhause gases over 1500 degrees. diesels burn much cooler and don't emit the same pollutants as gasoline. thats why there is no need for them to have cat converters.|||i would feel bad. did u know that most big rigs that are out there on the roads all day and night don't have catalytic converters.

How important is the catalytic converter? Can't i just do away with it?

My catalytic converter is stoped up on my 03 olds alero. Can't i just have it choped off and drive on?|||1. You are probably breaking laws without it.


2. Performance of your vehicle is poor.


3. Without converter your vehicle pollutes much more.





Enough?|||if there are emission laws where you drive, no. otherwise you can try, but not all modern vehicles get the same mileage without it.|||Have it replaced and find out why it is plugged. Your car likely has an O2 sensor behind the converter that will read in error and cause the car to run poorly without the converter in place. The fact that it is a federal crime to remove it is also a concern. If a shop is caught removing one, they face huge fines

Can I block the Catalytic Converter hole in my 1993 Grand Cherokee?

I have rattling going on in my catalytic converter, I bought the new one from Schuck's but the one they gave me has a place for the O2 sensor after the Cat. The one in my truck has the nothing after the Cat. Can i just put a bolt in the hole?|||yes you put a bolt in the hole and tighten|||If you need to modify it, It's best to take it down to a muffler shop where they can weld a piece of piping on. chances are if that area for the o2 sensor means it may be too long anyway. They could either put a patch over the hole or cut of a small section of the pipe altogether to ensure it's the proper length.





To be honest, they probably wouldn't even charge you but 20 bucks to do it.|||Go back to the store and check if they look up the right one. If that's what they have, then go to another store and get the right one.





btw, yeah, you can just put a bolt to plug it up. Doesn't mean one day it won't rattle off.

Is it worth it to replace the catalytic converter in a 1988 Oldsmobile Cutlass Cierra?

It didn't pass inspection. It has 70k miles (or so the odometer says) and doesn't look so good cosmetically? Is it not worth the $400 or so to replace the catalytic converter. I don't have a lot of money, and would rather not if the car is a piece of crap anyway.|||well if the catalytic converter is the only problem then yeah it's worth it cause it converts exhaust gasses... You either drive it or don't...|||I'd say, go for it. Even if the car isn't "worth" the $400 or so, at least you'll get a few more years out of it. Since it didn't pass inspection, chances are you're not going to junk it are you? If you are, with what will you replace it? Another "junker" that may or may not pass inspection?|||It SHOULD NOT cost you that much to replace that converter maybe $125 if that will fix it -do it....You do not need to replace it with O.E.M. use after market|||yes it is where are you going to get a car for 400 hundred that you know if you can install it yourself less then 100 bucks may get a little dirt your eyes but should be able 2 cut the old out with a sawz all and clamp anew 1 on|||well i think you answered your own question. if you dont think the car is worth it and can find another beater for the money then dont fix it. example: a girl just bought a car recently for $1,000 and then brought it to my work to be inspected. well when all was said and done she put an additional $3,000 in to it. now is the car worth $4,000. probably not. she would be lucky to get $2,500 if she sold it right now. i guess my point is dont waste money on something that is not worth it.

Can you bypass a catalytic converter on a 2000 Chevrolet blazer?

It has a vortex motor. I dont know much about cars but someone told me that some vehicles can have the catalytic converter bypassed, just wondering if this is possible on this type of vehicle.|||Sure.. You can remove the cat, but it's not legal. Some shops won't even do a service like that, or atleast would want you to sign a waiver.|||Sure, if you want a $10,000 fine. It is a federal offense if you remove any properly functioning OEM emissions equipment from a vehicle, including the catalytic converter. Most states have a limit on how much you can be fined, usually between $1000-1500, but the federal law sets the fine at $10,000. Also, shops will not do this kind of work because they will get fined a minimum of $10,000 in just about any state, and can be up to $100,000, and this is for EACH offense. Imagine if they did it to just 1 car a day for a year, how much that fine would be. Realistically, unless the cat is bad, you aren't going to gain anything by bypassing it.

Where can I find a low price catalytic converter?

I need a catalytic converter for a 2001 Pontiac Grand Am. My car is from California so it requires a specialty part, something to do with the emmissions in Cali. I can't find anything online.

The dealer will rock you if you try to buy from them. A catalytic converter is not anything exotic though they play it off to be. All auto parts stores can order generic catalytic converters based on the original dimensions (length X width) and the diameter of the exhaust pipe that enters it. Any muffler shop will easily install it for you. The scrap yard nowaday will probably not have one since they can fetch $30.00 to $200.00 bucks for an old one!

Does a 1997 Eclipse Turbo need a catalytic converter?

I bought a 1997 Eclipse Turbo that does not have a catalytic converter. Do I need to install one. I have some white smoke coming from the tail pipes. Is this the reason? Head gasket is fine, no oil leaks.

Is it good to straight pipe your catalytic converter in your car?

My catalytic converter have gone bad in my 2004 ford taurus, I have been told to straight pipe them but im afraid that it will just cause more damage then help. I was wondering what straight piping my car would do to the engine? and does it ever really help to straight pipe it?|||It would cause your vehicle to be very loud. It is illegal to run a car without a catylitic converter when it came with it originally. It would also effect your MPG due to the oxygen sensors not getting the same readings as stock.|||Is it good?





Try, it is *very* illegal. Like violation of *Federal* emissions laws. But hey, it's your a$$ not your lame-brained buddy or whoever gave you the bright idea.





How do you know your cat has gone bad?





If you pull the cat, you will totally screw up the O2 sensing on the vehicle and who knows what type of fuel mixture the computer will generate. There is typically at least one O2 sensor prior to the cat and one after it. The two sensors compare to one another and from this info the engine management computer calculates a fuel mixture.|||I don't believe so

What happens when your catalytic converter goes out on your car?

my mom has a cadillac esv and her catalytic converter went out. what will happen? how long do i have to fix it? and will it hurt the car even more to drive while its broken?|||MOST PEOPLE do not know when a catalytic converter breaks, so what is it that makes you think this, if it is an engine light, it could be an internal engine problem, that was picked up in the oxy sensor in the cat, or did you like run over something and break it? this needs to be repaired as soon as possible as the car was designed to run with one in working condition. take it to a muffler shop and have one installed, it takes about an hour, probably less.|||It will fail an emissions test. The CC has no other effect on vehicle function than to 'clean' (convert some harmful molecules into less dangerous ones) the exhaust before it exits the vehicle.





Unfortunately, you will likely have to take it to a muffler shop to get this changed as they are designed to be 'irremovable' in order to deter tampering.|||when your cat goes out the check engine light will come On. Your gas mileage will suffer.....yeah you can drive it but fix it as soon as you can to get better mileage and avoid the rotten egg smell

Can driving a car with a bad catalytic converter cause engine damage?

The car still runs and drives fine, just makes loud exhaust noise because of the cracked catalytic converter. I was wondering if it was safe to keep driving the vehicle, or if it may cause engine damage by driving it long distances like that.. Please let me know, I don't want to blow anything up lol.|||Your gas millage will decrease and you wont pass emissions. Temporary is ok but you should get it fixed. The sooner the better because it will save you gas money in the long run.|||Driving the car with a bad catalytic converter will not make the car blow up. All it will do is make a weired sound. You could run the car without any exhaust at all and would not hurt the car but would sure be loud. I would make sure that the converter gets changed quick because if the car is newer then 1984 then if a cop finds out that you are running the car with a bad converter then they can go right to your window and take your inspection sticker off and have your car impounded so I would not blow off getting it fixed. If would like to talk to me for a little more help then you can email me at supersport69@ymail.com.|||Yes, it will. Its a little costly, but you need to have that thing fixed. I ignored one in a Ford that I used to drive, and it turned cherry red one night and nearly wrecked the whole engine.|||it will burn your valves up causing major problems. but it would take it awhile for it to do that but i wouldnt drive it everywhere i go for a long period of time.|||Won't cause engine damage. It will not work as effectively at reducing harmfulemissionss into the atmosphere

What can i do about a clogged catalytic converter?

my catalytic converter is clogged, can i repair it or do i need to replace it?|||Catalytic converter internally looks like a honeycomb. It is made of ceramic and can break if hot and submerged in water or run through a car wash that sprays cold water under the vehicle.


Or could have gotten clogged by carbon from a poorly running engine.


Either way It will have to be replaced, there is no unclogging or rebuilding of this part.|||Unfortunately you will have to buy a new catalytic converter. What has happen is the ceramic material has melted together and no longer purging the fumes of your exhaust. Sorry for the bad news. Some mechanics will tell you to either remove you catalytic converter and just put straight pipe but once you do that then you will have problems with your 02 sensors. Plus, in most states, a missing or modified catalytic converter is illegal. Catalytic converters, when operating properly cleans a lot of carbon from the exhaust.|||Some people have been known to cut the pipe after the converter,ram a pipe inside it to break up the honeycomb,start the engine to blow out the pieces,then reconnect the pipe.This is probably illegal in some circumstances.|||Only legal way is to replace it.

How much would the catalytic converter replacement cost with labor on a Mercury Sable 2002 ?

How much would the catalytic converter replacement cost with labor on a Mercury Sable 2002 ?|||It depends on what shape the rest of your exhaust system is in because if a pipe has rusted or needs replacing or the muffler has rusted out that has to be fixed as well .

Is it a big deal if my catalytic converter sensor is disrupted?

my friend is a mechanic and check it out on the computer and it says it's the catalytic converter sensor is disrupted. he told me it's no big deal. true? i personally just don't like having the check engine light on. should i get it fixed and how much will it cost?|||no, just when you go for the clean air test|||The oxygen sensor error code he read out of your computer doesn't necessarily mean that oxygen sensor is bad, and can mean that the engine's running too rich or lean or the catalytic converter isn't funtioning like the computer knows it should. There's a risk of damaging your expensive catalytic converter in some cases, so if you want to know the real problem, get a diagnosis from your car dealer even if it costs you a labor hour to get the repair quote. Then you'll know how expensive it will be to fix and you might even fix it yourself once the problem has been properly diagnosed by the dealer.

How long would it take to kill yourself in a car with a catalytic converter?

I don't want to kill myself, but I read a story where a guy tried to gas himself in his car. He sat in it for thirty minutes with a hose from the exhaust pipe feeding into the car and still didn't die. The explanation was that the car had a catalytic converter. Is that possible?|||It was a story.


Probably got a free beer for the story.





A cat reduces the amount of CO that is emitted out the tailpipe. But it is never to zero. There is more than enough bad gas remaining to do the job (compared to a vehicle that does not have the device.)





Any carbon based material(paper, plastic, rubber, gas, oil, wood, tobacco, dope) all give off Carbon Monoxide.





Chemical fact you can confirm with a chemistry teacher(trouble with asking a teacher is that they will probably ask you to figure out the Molar volume of burning 20 grams of substance X (this was slide rule calculations) and chemical formulations.|||no, that wasnt the reason. cabon monoxide will kill you, even if you drive your car into a garage and then shut the car off, it could be deadly...its serious sht

Can i sue the previous owner for taking off the catalytic converter?

Someone told me that I could sue for this. I definitely know that it is a large fine, and now I have to pay to get it fixed. Can i sue?|||No. When you buy a used vehicle, unless there is a written warranty clause in a contract you sign, you can not sue or demand repayment for the converter.





However, you probably should have looked at it closer before you bought it. It's your responsibility for not checking.|||you couldnt tell from the sound of the car that it had a modified exhaust system? i would think that convincing a judge of this would mean you would have to provide some proof that the sound of the car with the header sounds no different from any other scion.....that may be tough to do.

How do you gut a catalytic converter?

How do you gut a catalytic converter and is this legal? Or would you have to either get or new converter or can you put these parts back into it for inspection?|||There are quite a few things you can do. To keep it legal, you can buy a high flow catalytic converter. It is less restrictive and you can pass inspection with it. On the other hand you can get a Cat Delete Pipe which is a straight through pipe which you can replace your Cat and when inspection time comes around you can put the stock cat back on. Remember that if you are caught without a catalytic converter it is an EPA issue and can carry heavy fines so I recommend the High Flow Cat. I have one on my car and it works great. You will only gain 3-6 more hp with the cat delete so might as well stay legal.|||It's fairly easy to hammer loose the delicate ceramic honey comb inside a converter but bare in mind if your state requires a converter for the year of your car don't do it!

Where and How to obtain a Catalytic Converter for calif. OBD II?

Where or how should I buy a replacement catalytic converter for my 2000 Chevy-s10. My catalytic was stolen, not damaged. And I will not still one either. I read the following off the internet, but I want to ask real people like you. What should I do? Any sites? Any personal experiences?





Any catalytic converter offered for an OBD II equipped automobile (mostly 1996 and newer vehicles) is legal for sale in "49 states", but not in California.





The California Air Resources Board (CARB) has not certified any new, aftermarket catalytic converter from any manufacturer for use or sale in California on an OBD II equipped vehicle.





Until CARB certifies an aftermarket converter, no company can legally supply a new, aftermarket catalytic converter for OBD II equipped vehicles for use or sale in California.|||Have you tried going to the Chevy dealership. GM should be able to get you an OEM converter.|||I dont think that is true. Many companies and exhaust business sell or replace catalytic converters. OBDII came in around 1995, this is a huge amount of vehicles you are talking about. I know companies make aftermarket OEM cats for pre 2002 and other vehicles. I like the quality of dealership parts, but it will run you around $600-700 for the part alone. I just got one for a 2001 Pontiac 2.4L and it was $650 after a discount. The vehicle passed CA. SMOG with the cat on it.|||check muffler shops like Midas and Meinke and see where they get their cats from... If they say dealer only item.. unfortuneately that is what you are looking at..

What is a Catalytic Converter from a car?

I took my car in the shop and they told me that my car needs the catalytic converter changed. What is that? I have a honda accord 03 they are charging me to fix it $500. Is that right. How much is that piece in the auto parts if I go get it?|||03 Honda Accord part #18160RAAA11


Dealers list price $633.98


They offered you aftermarket part, so $500 with labor sounds OK.|||It is part of the exhaust system and the cost should include the disposal of the old one as well as the price of the replacement.|||a catalytic converter is so expensive because it is made with Platinum.


They should cost about $150 retail. it is on your exhaust and it burns up excess fuel coming out of your engine to reduce emmission.





Shop around, $500 is too much|||the catalytic converter is a small box in the exhaust just after the engine. what it does is take nasties in the exhaust gas like carbon monoxide (CO) and nitrogen oxides etc and convert them into gasses such as carbon dioxide (CO2), and water (H2O).


they are very expensive because most of them contain precious metals such as platinum in them.


they DO NOT burn up excess fuel. they are actually damaged by excess fuel, and as a result cat converters are often damaged by rich running engines.|||yeah i would say that 500$ is too much to buy you can sell a catalytic converter from a car that is old and doesn't work for around 75$ to a scrap yard so they are a little pricey considering the Platinum and copper used in it.|||There is no way that you would need you catalytic converter changed on a 03 car. Espcially a honda. Seems to me the shop is trying to rip you off. Like other have said its in your exhaust system. Look under your car follow the exhaust off the manafold to and you will see a small thing that resembles a muffler. after the catalytic converter you will find the actual muffler which will be larger... then the end of the exhasut pipe. (I CANT STRESS THIS ENOUGH GET A SECOND OPINION) I would be hard pressed to think you need a new catalytic converter.... Why did you have the car in the shop to begin with??? (The cost isnt in the converter itself... legally it needs to welded into place because they are not to be removed...your cost is in the labor.)

What can I expect to pay to replace a catalytic converter?

I have a 2003 Mitsubishi Lancer at 115,000 miles. Had a guy do a diagnostic and was told the catalytic converter needs to be replaced. I don't mind paying because I need this car to run well for me. My question is, how much can I expect to pay, parts and labor. I live in San Diego if region makes any difference. Thanks!!|||There is a good chance that there is really nothing wrong with the one you already have. Many times, a converter will get clogged up when the fuel mixture goes wrong. THis creates extra unwanted hydrocarbons that jamb things up. Here is what to do. First, buy a can of spray Gum-out. Open your hood, and find your IDLE AIR CONTROL VALVE. On most cars, it is very easy to remove and clean and then re-install. While you are at it, remove your air intake snorkel, and clean the throttle body. Put things back together, and start the engine. Find EVERY vacuum orifice, and insert the nozzle from the Gum-out into ALL of them. If you are clever, you will be able to figure out a way to insert the nozzle underneath the intake boot. SPRAY, SPRAY, SPRAY!! Run the engine and spray directly into the intake system. THis will remove carbon from the valves, piston tops, and rings. It will also clean out the O2 sensors, and shock them into working right. Also, it wil clean the debris from your converter. A couple of cans at $3,00 each will usually repair the damages already done to the converter. The CAUSE of this problem is re-condensed engine oil vapors. You are best off by using an engine cleaner, and switching over to a good synthetic, that won't make ANY sludge. GOOD LUCK!!|||The best answer for that, being it can vary depending on the mechanic/tech. Most common labor on a vehicle is around $25.00 an hour. It usually takes around 2 hours or so for most mechanics to change it. As I have seen, a catalytic converter usually costs around 50-90 dollars for semi-modern model cars to new cars. Being that yours is a foreign made vehicle, it could cost close to double that. Hopefully I helped.

It is very rare for a catalyst to fail after 8 years (in fact, there is a federally mandated 96 month 80K mile warranty on catalytic converters) but I could believe there is a sensor integral with it that is bad.

The light just came on, but we can't get the car back to the shop for a week. Is if okay to drive the car for a week before replacing the cat? Is it dangerous or will it hurt the car?|||Hey... Dont worry too much, if your Lancer still has power. If your catalytic converter is clogged it wouid be similar to "lugging" a car up a hill in too high of a gear. Thats harmful... and can burn out your valves, or engine. There is a concern ... you wont be able to pass smog with that check engine light on, so hopefully that new cat will take care of all the saved codes . Hope this helps.|||It is okay to drive the car.

Thanks ever so much!|||Gypsies stole it? Haha that sounds funny-sorry.


But i wouldnt try a used exhaust part-you really could be wasting your time. Exhaust parts generally rust solid onto a car and together. To unhook the converter from the exhaust pipe might require doing something extreme like cutting it off, ruining the part. BTW, i hope they didnt ruin the rest of your exhaust system geting your old one off.


Just go to your local auto parts store. They generally will sell 2-3 different "quality" of products. They will sell the original manufacturer one-one that is actually made by whoever made your car-this will be the most expensive. Then they might sell a couple knock off brands-made by other companies yet the price is alot cheaper but still just as good of a product more than likely.|||http://shop.ebay.co.uk/items/__diesel-ca鈥?/a>

I have a feeling I'm being taken for a fool... I looked online and some of the converters that I saw cost about 250. How much should I reasonably pay for this repair?|||You're car seems fairly new to be needing a catalytic converter.Most converters will pretty much last the lifetime of the car.I'd take it somewhere else and get a 2nd opinion.|||go to an exhaust/muffler specialty shop. they are not as likely to rip you off. did you check to see if the cat might be warranty work?|||$2500.00|||First of all, you should never change the catalytic converter unless it is breaking up and rattling, or you simply can not pass DEQ without changing it.


A catalytic converter is not good for a car or the environment.


It basically takes soot (that they test for), and converts it to toxic chemicals like formalin, cyanates, sulfites, etc. (that they do not test for).





There is no light that says your converter needs to be replaces, and they are probably wrong in the diagnosis.


The O2 sensor is much more likely.


But even more important is to fix what is causing the converter or sensor to go bad, such as a bad plug wire.





Then you are being way over charged.


The catalytic converter is the easiest part of the exhaust system to change because it usually have a simple flange with external bolts.


Labor should only be $50 to $75.


The converter is only $107 on the internet.


Even if you live in California and need the dual sensor one, it is only $251.


Midas is charging more than double what it should be.


( but it is true retail should always be at least 30% more than the internet, because there is a better guarantee)





Find a good mechanic you can trust, and don't assume the light going on means you absolutely have to fix something. It is just something to have looked at just in case. Check engine lights go on and off all the time, from simple things like going up a steep hill. It does not mean there is something for sure wrong.


Don't go to a muffler shop because they will just want to try to sell you exhaust parts.


A real mechanic will determine if anything actually needs to be done, not just sell you something you don't need.

Is it a good idea to remove a catalytic converter from a vehicle to gain HP?

I just installed a Borla cat-back exhaust system on my 04 Hemi Ram. Does anyone recommend I remove my catalytic converter to improve HP and/or sound? Thanks.|||first off this procedure is more tricky than u want. i dont recomend it but i cant saymuch i removed it from both my dodges... yes it will improve sound alot. a whole lot no one can denie that. sumtimes it will make it louder though and not better depends on your muffler your using for sound other wise it wont sound good, just noise annoyingly and get you in trouble. some state's require the converter to pass its emissions testing so think about that as well. and also there is oxygen 02 sensors before and after the converter. the first one before the converter reads the fumes and will tell how rich it is so it will modify your fuel/air ratio so if its not working your truck will run a lil worse and will use a whole lot more gas. the second one will sniff to see if the readings are different so it tells if the converter is working or is on and it will set off check engine lights if they dont work. they do more than that but thats just a short break down of it. ull get worse gas mileage alot worse than u think. and might make it run different too. sum it wont affect how it runs sum it will. sum people try to put the sensors back in the straight pipe itself but then the rear one still needs to read diferent than the first so u might need a non fouler or sumthing like to make it give diferent readings to push it away from the fumes. of course they also add in the 02 bungs too., so i dont recomend it but i do it just cause i like the sound without it.|||no its a federal offense plus on top of that you won't be passing any emissions test with your truck (if you have emissions) on top of that you have O2 sensors placed throughout your exhaust reading your exhaust fumes O2 sensor A (before cat) needs to read different then O2 sensor B (after cat) if they don't equal out you will have a Check Engine Light on with an extremely rich exhaust the gas mileage will be HORRID. shal i go on?|||No. Not only is it a big federal offense (fine for getting caught is typically $10,000 - $25,000) but it makes no noticeable difference in performance.

Catalytic Converter?

Why do people think it is bad to cut off the cat and replace it with a straight pipe. Other than the sound. It doesnt do anything to the motor does it.|||Well, the EPA is really hard on vehicle emissions. The Catalytic Converter helps out by reducing the amount of polutants that are created by burning gasoline. You could get fined for removing it and you risk not being able to pass your vehicle inspection. On another note, catalytic converters have a habit of collecting carbon deposits which in turn hinder your exhaust flow, causing loss of power and a warmer running engine.|||It's bad because IT'S ILLEGAL!! Tampering with an emissions control device is a federal crime.|||In newer cars, yes. It does bad things to the environment, also. Not to mention that a spot inspection from the State Patrol or police will result in a $5000 fine. Are you that selfish moronic that you don't consider others?|||Because it is illegal and it interferes with the cars emmissions.





If a car fails an emmissions test it fails its MOT.|||Were I live there Is no DEQ This means emissions test there for you can cut off your cat and not be eligal. So check local state laws before jumping the gun. The reason you should keep the cat besides the emisions quality is that it helps produce back presure Most people remove the cat thinking it will make them go faster when infact it does the oposite in ost cases.

Catalytic Converter?

I Have A 1994 Honda Accord , I Believe My Catalytic Converter Was Clogged Because It Was Running Like Trash , So I Cut A Few Holes In Tha Catalytic Converter For Better Breathing , It Runs Better , But It Will Stall Once I Park , So Are My Holes Not Big Enough ? Or Do I Also Have A Bad O2 Sensor ? Im Changing Tha Cat On Thursday And Possibly Tha O2 Sensor If Thats Also Bad . Please Dont Give Me Some Stupid Answers Like Why Did You Cut Holes In Your Cat , Um Hello Cuz It Wasnt Running Good ! ! ! Anyways Thanks For All Your Answers !|||Your car, like all other small cars, needs backpressure to run correctly. Backpressure is the force created by restrictions in your exhaust like the muffler and the catalytic converter and the actual size of the exhaust tubing. Your converter maybe clogged, but that is not going to hurt your cars performance that bad, if the O2 sensor is bad, it will tell the computer a false reading, so it will make your car run leaner it will run more air and less fuel in the mixture, ultimately running bad. Do you have a check engine light on? This can tell you if it is getting a bad reading. And if your changing the cat just go ahead and get the O2 sensor while your doing that.|||i would change them both and then see how it runs. that could be the problem, or it might be something more, but start with the things you know are bad before waisting money on other parts.

Catalytic Converter?

My check engine light came on. I took it to autozone and they did a diagnostic on it. It came up with a code saying that my catalytic converter is bad. It seems like an easy replacement, but will the replacement make my check engine light go off automatically if its fixed, or will I have to get it reset? and where?|||When you change the catalytic converter, if they don't reset the codes at that time, the light should go off in about 40-60 miles, when the computer realizes that it is no longer an active fault. It will still be listed as an inactive, or passive fault until it is cleared by a mechanic.|||You can reset it by removing the positive battery cable for about half an hour. When you replace it, start the car, and the light should be off.|||If that is what is causing your fault, then all you will need to do is take it back to autozone and they can clear you fault, or if you have someone change the cat then, they maybe able to clear it for you.|||after you get it replaced, you have to have the codes erased.

I have a 2000 vw passat and I think my catalytic converter is broken. I turned on my car one morning and my engine light came on but was flashing and smoke came out the exhaust. I turned off my car and never turned it back on. Its been two days since then. My question is it safe to drive my car?|||Im almost sure that your car wasn't producing smoke as you say! every morning all cars (especially if you are in a region with high humidity) produce apart from the smoke and some steam (it is the humidity that was on your exhaust). it is not used to see smoke caused from burned engine oil on the exhaust exactly after turning the engine on.


this model usually has problem with the lamda sensor. i think that when your fuel isnt good then this light is (on this model)|||If the light is on then that means your cat is going bad, it is still drivable although it is illegal to, the whole purpose of a catalytic converter is for the reduction of exhaust pollutants. It will not harm your car if smoke is coming out of the exhaust, it just means that the catalytic isnt doing its job, just like diarrhea hehe, your big intestine isnt doing its job, but still comes out fine. My advice would be to replace it asap so your o2 sensors wont fry out from the bad smoke. It is fairly cheap to replace also, it cost me a littler over 200 for my Impreza, goodluck!|||You did yourself a big favor by turning the vehicle off right away (most people wouldn't) Any time the check engine light FLASHES on a 1996 and later vehicle it means that you have a misfire that is severe enough to damage the catalytic converter! And the most common thing on the VW to cause an overly rich mixture is a ruptured fuel pressure regulator diaphragm allowing raw fuel to be sucked into the intake manifold. This is a lot cheaper fix than replacing the converter (About $1800.00 for a new converter on this vehicle)|||good job!! that is exactly what to do, turn the car off, and call the repair shop (I sure hope you have triple AAA if not, I suggest you get it if your car is more than a few years old, it will save you money in the long run I promise. Your mechanic needs to check out the car and diagnose the problem, I have answered several questions in the last several days where check engine lights come on, and they kept driving, and then something went really wrong and the car stopped in the middle of the freeway, when they should have turned the car off when the engine check lights pop on.


This is what check lights are for. Do not drive the car. ask a friend for a lift somewhere. best of luck.|||Try again. A bad cat doesn't cause smoke...





Is it safe to drive?

Catalytic converter?

i was wondering what exactly is in the catalytic converter on the cars and trucks.|||A "cat" contains a honeycomb pattern insert made of platinum and rodium, when hydrocarbons and carbon monoxide flow through with exhaust temperatures and oxygen they are converted to water and carbon dioxide. American cars no longer have air pumps installed, instead they have an addaptive strategy in the control module programming that switches the fuel mixture rich to lean about every second. This charges the cat with oxygen to catalize unwanted gases, also this gives the ECM the ability to test catalyst efficeincy by monitoring oxygen sensors before and after the cat, if there is a matching pattern on both sensors, the catalyst isn't working. A misfire can load the cat with fuel and cause extreme overheat and meltdown of the cat.|||A catalytic converter (colloquially, "cat" or "catcon") is a device used to reduce the toxicity of emissions from an internal combustion engine|||Inside a catalytic converter is a fibrous material that helps reduce the amount of pollution released to the atmosphere. If a car fitted with a catalytic converter starts to burn oil the converter will eventually block up and usually cause back pressure in the exhaust system and can cause cracked exhaust manifolds|||it contains small amounts of platinum and ceramics that heat up as hot exhaust goes through and gets even hotter burning off unburnt hydrocarbons and reducing emissions,cars with an air pump pump air into the catalyst to add oxygen and make it hotter for a more complete burn.the cat concerter basically burns wasted fuel from the engine.hope this carifies it for you!!

Catalytic Converter?

The purpose of the catalytic converter?





A basic explanation of how the catalytic converter functions?





A description of the compounds involved?





The advantages and disadvantages of using the catalytic converter?





do you think the government should mandate that all vehicles sold in the United States have catalytic converters? Why or why not?|||It uses platinum or other precious metals as a catalysis to convert nitrogen oxides to more harmless chemicals, and carbon monoxide to carbon dioxide, and any hydrocarbons to CO2 and water.





advantage: converts pollutants to less harmful chemicals


disadvantages: expensive, can break, requires computer controlled lean burn engines.





The government (in the US anyway) already does mandate it's use (I think, or else they mandate the levels of pollutants so low that a catalytic converter is required to meet those limits), and they should continue to do so to as long as needed.

So my mom has a 1995 Mecury Villager (I think its just a rebadged Quest). So anyway, I was just wondering generally if I buy a universal type catalytic converter (CC) or even a CC for a Nissan Quest...would there be molding required (and whats the typical cost for that).

Catalytic converter?

Catalytic converter can change NO2 to N2? I mean, if there is no carbon monoxide, can the converter still do it?|||Sorry, but Robert is not right.





the catalytic converter makes certain reactions go faster. Many of those involve the reduction of nitrogen oxides, either NO or NO2. But a reducing agent is needed, and it is usually CO, HC (unburnt fuel) or H2 formed in small amounts in the complex reactions.





Unfortunately the catalyst does NOT catalyze the decomposition of NOx, only its reduction.





That is one of the reasons why the fuel to air ratio is so carefully controlled, so that you have enough reductants to do the reactions but not so much that they also pollute.





Does that help?|||Yes.


They complex platinum/rhodium (sometimes with palladium) catalyst will reduce the NO2 (or any oxides of nitrogen) produced regardless of whether there is any other material that needs to be oxidised.





2NO2 -------%26gt; N2 + 2O2





Generally 2NOx ---%26gt; N2 + xO2

I have a 1989 Ford Probe (yep very old car!) The other day, the Catalytic Converter just fell off .....well, first of all, why this happened!! I have had lots of problem with my car but nothing ever just came off or fell..... So I took my car to the shop and I got an estimate of $550 including Cat, joining pipe, gasket and labor. Is this a reasonable price? I shopped for the catalytic converter on line but it was not that expensive, $150 average. Since this car is very old and I don't really want to spend too much money fixing it even thou I love my car. Should I visit some more shops to see if I can get less?? If I just let it be without it, would I get more problems? Please advise! thank you|||Since i am not a certified mechanic,,I will answer.





I would just patch the area between that and the muffler. If you don't live in a state or county that has emission inspections I would do it... And for all the tree huggers It has never ever been any proof that exhaust emissions lead to global warming... They got rid of regular leaded gasoline and added these catalytic converters... and apparently it still doesn't matter... So if you can get away with just welding a pipe in its place do it... I know of quite a few Mustang GTs that have no cats and air pumps disconnected and it only made them run better... IF you must get it fixed for emissions reasons.. I would buy a Cat yourself,, and go to various garages that can weld it on... You should have to pay more then $50,, I have had plenty of things welded and it was only $20-$50 .. You may want to avoid exhaust places Here,, because they would just love to sell you their stuff.. IE that $450 ,,, ching gow you should be able to get duals and stainless at that for that much...

Disconnecting Battery to clear bad oxygen sensor and catalytic converter?

I am trading in my car and the check engine light is on because I need a new catalytic converter and oxygen sensor. If I disconnect the battery and clear the code, how far do you think I will be able to drive without the light reappearing?|||Depending on the car, disconnecting the battery will likely not clear the code at all. Most OBDII cars store emissions faults.





If you did clear the code, it would likely come back relatively quickly, either a failed O2 sensor or a failed catalytic converter is going to get picked up very quickly. My guess is maximally you'll have 10 minutes, or 5 restarts.





The dealership is likely going to have to emissions test it for re-sale anyway, and they're going to discover this. I would suggest just turning it in with the light on, it shouldn't be that big of a problem.





I also think it unlikely to have both a failed catalytic converter and O2 sensor, the catalytic converter failing would signal the O2 sensor, the O2 sensor failing would mean nothing else.





At the end of the day we're talking about $30-$60 for most O2 sensors, $100-150 for a catalytic converter, and 1 hour of labor. The dealership really shouldn't care, as they have to invest more on average in preparing a car for sale.|||It depends on your car's computer.





I know in my Ford Escape, because I don't have the money to buy new catalytic converters at the moment, I've been resetting the computer, and I can usually get about 400 miles without the light coming on.|||Depends on how bad it is. Disconnecting the battery will not work though because of a capacitor in the computer. If you take the cables off and touch the lead ends together for about 10 minutes it will drain the capacitor and clear the codes until they set again which could be at anytime. AutoZone will clear the codes for free with a scanner though.

And I won't even mention the fact that other people care more about breathing clean air than they do about whether your car rattles. |||yes your check engine light will come on. Cat converters don't rob power like they did in the early 80's. Just have an aftermarket one welded up at a muffler shop. If you are concerned about power just get a performance one. good luck!|||its illegal depending on where you live i cut mine off and i still passed inspection it sure feel goods living in the south plus you will get added power with it off |||you will go to jail with murderers and rapists. your car will run bad.

Could a catalytic converter cause your car to overheat?

My car overheated and it blew my engine... Could a bad catalytic converter cause the car to overheat and blow an engine?|||very unlikely. did you have any antifreeze in your radiator?|||A catalytic converter (CC) has a chance to make overheat the engine. A worn cc will block the exhaust gas, by not moving out hot gas, the heat will be take place where there is an air to blow the heat which is engine block. Even the engine use coolant, the coolant has it's capability to absorb and release the heat. But, a worn cc will shown by deep sound of blocking way of gas, and hard to accelerate. Do you experience those? Please check the coolant changing time, coolant level, work of fan, and heat of the radiator. If the gauge show overheat but radiator ply is cold, a jam thermostat is happening. If the gauge is overheat and the ply is hot but coolant reservoir is same as cold, a worn of radiator cap is happening. Other then those two, please check the coolant and fan. If fan not work, replace it after the wire and fuse being check and those is fine. If the fan not work but work after a bit hit, a dirt is blocking the fan blade to turn, clean it with penetrant.|||not really the cat is full of plaitum and they are beads and are used to filter the exhaust.


they will weld together not letting the exhaust flow properly.


and they will get cherry red when this happens but to blow a engine not likely.


it is possible that you spun a Bering because of lack of oil and it may have even threw the piston .


you would have to ask the mechanic what happened to the engine.
