It'll be fine, just get a converter. However, I can assure you, your exhaust is not 2". Even mine isn't. I betcha it is 2.25" maybe 2.5" Measure it, then grab the appropriate converter. You will probably have to cut out a little more of your exhaust piping, but that'* not a problem. You will also probably have to have it welded in, versus just clamps [sorry, you lose].

Well I wasnt talking about the Bonne I was talking about a 1990 Cavalier that I may get soon to replace the Bonne.

so is there a certain one i need. I have noticed that some have air plug ins or something. Will this one be fine or will i need a different one http://cgi.ebay.com/ebaymotors/ws/eB...sPageName=WDVW

Somebody with a 92+ can help more with this, but the 92+ OBDI emissions system consists of at least two O2 sensors. One before the cat [used for the Air Fuel Ratio], and one after [used for confirming a properly functioning catalytic converter]. The first one, is in the headers, so don't worry about that. The second one, however, I do not know if the O2 Bung is mounted on the cat, or on the exhaust after it.

ok thank you very much could someone please enlighten me.

Dont worry about the 02 sensors. Just find one for your car, thats all you got to worry about.

I got the 94006 and it doesnt have that air tube thing. Id suggest you get the same one.

ok, the 95'* only have one 02 sensor and its in the rear exhaust manifold so ya got nothin to worry about. you also dont need the air tube so id definately agree with CmptrNerd and recommend you go with the carsound 94006 cat. heres the cheapest place around to get one... http://www.justmagnaflow.com/Catalyt...ters/94000.htm

only $57.69 and free shippin since its over $50
