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. And of course the check engine light will stay lit with a P0420 code.|||Just get an aftermarket hi flow cat
