It will be VERY loud, even with a converter, but you should notice a little boost in power. The biggest gains would come if you remove all of the converters.

3.5 in. is too big for an N/A. You would have no backpressure to keep the motor going. On an N/A, the biggest you should go is 2.5 or 2.75 in.

racing beat just released a cat back for the N/A's. It looks really nice.

I will probably end up by this exhaust system when the time comes.

not trying to be offensive, but do a search on the word backpressure here. you will learn some cool stuff.

Hmm...thanks for in input guys. The reason I even asked is cause I noticed that at one site they said it was for a turbo and on another it said any 86-91 would work.

This friday I'm getting the car smoged then we're removing all the converter and vacume crap...then installing the custome header (racing beat knockoff) then going with the 92-96 prelude cold air intake systew with an A'pex'i filter then followed by this exhaust system We're talking about.

I'm hoping it's not TOO loud...but just loud enough to hear me coming from a distance. Last think I want it to get pulled over and get a ticket for the mod.

If this all works, I'll let you know.

It will fit, but the GT spec is INSANELY loud you better have a really good stereo.
