I have a 91 non-turbo, needs the exhaust system replaced. Any tips or recomendations or where to get one?

 

do you mean just muffler? or the whole entire system from header back?
Well alot of people would highly recommend RB even myself recommend RB.

 

RB all the way, im sure the true duals is probably loud as hell though. ive got RB turbo back on my car and it sounds great.

 

RB. I've got the cat back and it sounds good but a bit quiet. I'm gonna get the 'downpipe' and presilencer to add a little more power and sound.

 

I've got the RB downpipe and presilencer with the catback exhaust and it sounds really nice. Good tone, no raspyness, loud up top, quiet down low.

 

meh, who needs exhaust? Run it straight from the engine. Ports to atmosphere. That's how you get it really loud.

I'M KIDDING!!

I too support Racing Beat all the way. My set up is soon to consist of a RB header with my custom 2.5 all the way back to my Y-pipe then going to dual Apex'i N1 Muffs. But that's just me. I like it loud and rough. Oops, wrong thought process. I like my **** roaring.

 

GReddy Power Extreme Exhaust

I would hold out till you find someone selling one on here if you can its the best my 2 copper and its not annoyingly loud. They do not make it anymore so you will have to find one used.

 

I had the Power Extreme on my 91 NA.... it rocked... The tips are a little ricey LOOKING, but other than that, its fairly quiet. I also had the bonez high-flo cat as well... was a great combo. Quiet, powerful, and had a great exhaust note.

They are still available at rx7.com

Scroll to the bottom... They are still around while supplies last. I was tempted to get one, but the price was a little steep considering you can get almost the same thing/power/quiet for less from RB.

 

I'd say... imagine an exhaust exactly just like you want one, then get a local exhaust shop to make one for you.

As long as you get the right piping size, the rest doesn't really matter (tip and muffler wise, etc).

My ideal exhaust would be a right-sided single exit all-stainless exhaust with a semi-oval style canister (like, a canister but wider and sort of square) and a 100 mm tip (not grapefruit-chucker big but not restrictive either), and high-flow cats... except I'm not going to get a new exhaust until (if) I go turbo...

For an NA, I think piping over 60 MM would be a bad idea (unless I'm mistaken?).

 

Yea pretty much what everyone else says is right. Racing beat all the way. I myself have racing beat all the way with a corksport cat-back. The corksport is pretty loud and it becomes a flame thrower if you get it. Heres a video of what the corksport would sound like.
