whats the cheapest exhaust i can buy for the rx8 that sounds amazing would i need full system or just back box dont really wat to replace as far as the cat just back box would that still sound sweeT?

 

This is the cheapest one I could find that still sounds bad *** and has pretty solid build quality. One of my friends has this exact exhaust and its awesome for 499. I'm sure there's cheaper import exhaust systems around 299 on eBay but I WOULDN'T recommend those!

cool with the rx8s ca you buy them with out the cat backs as the car alredy has a cat doest it is the back box the only silencer on the rx8?

 

^Huh?

You can still buy a cat back. It just replaces what exhaust you have after the cat. Or you can buy a resonator pipe/race pipe/whatever to replace that, and of course, a header to replace your exhaust manifold.

As far as cheapest..

Race Roots single exit exhaust : $350 shipped.

Or the HKS Hi-Power single exit exhaust.

They're the two "cheapest" I know of. Again, as mentioned before, eBay "special" exhausts are not the way to go.

 

I would recommend the Race Roots Catback. I have it and absolutely love it. As MS Addict said it is 350 shipped. It is a single exit exhaust but sounds great. Go to the link below and you can read up about it. Go to the last page and look at the video I made to see what it sounds like.

Sounding "sweeT" is subjective, as stated above the Race Roots exhaust is the cheapest quality exhaust. Your second post is almost unreadable, don't want people to think your .
