I think one of the best exhaust is the Apex N1 exhast. It all depends if you want to keep the dual exhaust or turn to single.

The website that has it the cheapest in www.I-M-Racing.com or NOPI.com

I bought the Apex N1 duals for my '87. It's not installed yet.. but I bet they're gonna be loud as hell..(at least that's what I've heard others say) even with the silencers.. too bad I wasn't going for the loud effect.. damnit..

i've had the single N1 for 3 years...great system...



not loud at all........well, as long as you still have a cat

rx7machine

Ok.. then the duals shouldn't be too much worse, if at all.. I still have my cat..

RX7CMS

What if you have headers and no cats what cat back would you use to make it not as loud

rx7machine

I was going to get some Racing Beat headers but it was on back order forever..

Damn that's going to be loud.. maybe the RB catback..

RX7CMS

Yea I started it up with the headers only..it was real loud

Sort of different, but I drove my TII for an hour downpipe only! It was like driving a prop plane with no sound dampening!

Anyone know if the Rotary Performance Cat-back system is any good? I know it's the lowest price, and I saw in Rotaryman88's FAQ about staged mods for FCs that he listed that one as a good one. Anybody actually tried it out?
