Yeah that sounds like what I mean but i took it out. It did not have any wires or any thing so i did not think i needed it so I took it out along with the cat, was that a good thing to do?

Do you have a picture of it?? 1G cars don't have a rear/2nd O2 sensor...

So it would not be a bad thing to take out?

Pretty sure it is a resonator. What else would it be?

If so, then leave it in. It controls the sound of your exhaust.

*edit* Just thought of something. How do you mean "behind"?

Closer to the engine or the rear?

If it is close to the engine and your exhaust is stock, it is your flex piping. Your engine moves when you drive, the flex pipe keeps your exhaust from doing the same. DO NOT take it out.

Its the resonator, I just put a bigger exhaust on my 98 and there was a resonator right behind the cat. Controlls the sound of the exhaust. My o2 sensor was a few feet futher down the pipe.

Stock 1G's don't have resonators... at least all of them that I have seen. My 2g has 2 or 3
