cutting out the cat?

[ATCharming]

i was thinkin about cuttin the cat out of my car (92 lumina 3.1)... i know im not racing it or anything, so no flaming please lol

i live in a county that we have no emissions tests in. all cats do is clean up the air right? no benefits, just negatives, like robbing power, fuel eficiency, and sound?

am i wrong about this? i asked my shop teacher to cut out my cat and weld pipes straight to the muffler, and he said i shouldnt do it cuz it would probably hurt the performance of my car, due to loss in back pressure.

what do u all say?

im just tryin to make it run more eficiently and, hell, why not make it perform better.

it'll fuck up your PCM, it will give you a rich mixture at idle most likely unless you get an O2 sim which i dont know if they make for your car,

my 90' volvo has a major exhaust leak before and after the cat, so the o2 sensor gets like no readings so it makes the mixture rich as hell at idle, smells like a dirtbike

keep the cat, it's not worth the time or money to remove/gut it. it's a lumina for christ's sake...

well the thing is i wouldnt have to spend a dime on it. thats why i figured, what the hell, if all it does is good, and its free for me, then why not.

but i guess maybe not

For SS. I don't think it would be worth it on a Lumina.

ss said not to tho lol. so u agree with him. if i had to spend moeny on it, it wouldnt be worth it, but itd be completely free for me
