Catalytic converter...HELP PLZ...

My '95 Z28 had a clogged catalytic converter. I want to remove the cat. and replace it with a straight pipe. Will it run smoothly without the cat. converter?

Hi, ok smooth as in smooth ride or smooth as it doesn't shake or rattle.... from what I know, taking the cat out might confuse the comp. Then again I'm not that familar with the 94-97's as far the o2 setup is. But asuming is the same as mine (00) . By confusing I mean it might run a bit rich thus making it not as "smooth".

Thanks. By smooth, I meant that it would run without dying or backfiring and consistent idle. I don't see any Oxygen sensor on or after the cat. So I don't see how it would be a problem if it were removed. Then again, I'm not a mechanic.

What I would do is, since you say the cat is clogged anyways. Take it off and run it like that for a while and see if it make a difference that you notice, and if you think it improved then go with it. I do know that by removing the cats you also free up some power. I would do it on my but in Texas you need emissions. I've heard of o2 bypass but no one here has been able to confirm that.

It is illegal to remove the cat. Having said that though, it can be done without sacrificing the way the car runs. On a 95 there is no O2 sensor after the cat to monitor it. If you do it, don't get caught.

If you live in a DEQ'd area, you'll definitely want to replace it rather than removing it because you'll never pass your emissions test w/o it.
