i am buying a 92-95 honda civic and i was wondering how monza exhaust and header does on a civic? i put the big bore system on a dodge neon when i was 16 i liked it but never got the header, i am wanting to know about how much of an improvement it would make if i put monza; header, high-flow cat, and big bore exhaust system on?

It will sound good, dont expect crazy gains. Making the car breath better is always a plus.

What he said. :iagree:

I have a Monza cat-back on mine - nice sound, only marginal improvement. Combined with the intake and header, it's about the same as the gain you get when you're driving with the AC on and then you turn it off. But I've had no problems with it at all.

well i know its hard to gain much from exhaust ne way so i'll prolly go with the monza cat-back and get a dc header, at least i can pick up a little bit more from the header then.
