I've been doing alot of looking around, aswell as searching through the forums and I can't come to terms on an exhuast for my car. (04 RX-8)

I recently just bought a Greddy turbo kit, HKS EVC IV boost controller, turbo timer and whole bunch of other parts but I can't decide on an exhuast.

Any recommendations?

 

True 3 inch piping is what you need. Whether or not you gut the cat makes the biggest difference

 

if your looking for flow/performance, you dont wanna GUT the cat, you just wanna get a straight pipe...

 

The best exhaust out there I think is the Turbo XS Full 3 inch exhaust with race pipe. The only thing is you gotta extend the tips about 2.5 to 3.5 inches out! Thats the set up I'm running!

 

True about the tips. I just melted off some of the bumper

 

it needs to be extended 4"

 

borla and turboXS are the only 3in exhausts i can find.

 

you didn't look hard enough

 

So do you just ask the shop/installer to do this? (exhaust noob question)

what other ones are 3in? HKS?

 

The HKS Hi-Power is a single outlet and just a hair smaller than 3" diameter. I have it on my car and love it.
