best exhaust if i dont need any cats?
 

well where i live we have no emissions so i can have no cats
whats the best ?

HKS HIPER

n1 is bigger than the hiper and cheaper:D

HKS hiper titanium racing exhaust with 4" piping from the downpipe back :)

Greddy SP exhaust is the best with no cats.
I have tested most of the exhausts out there, and its the quietest.

:D ....someday i will buy that bastard.

HKS hiper titanium all the way. "THE BEST"

well the new HKS or the ASP Race exhaust (what i have) are the best if you don't need cats. Why because the mid pipe and exhaust are all one long straight pipe. Its also lighter than having both seperate.

glassman what the hell is asp?

It was a company (Kevin Wyum) that made parts for FDs he no longer makes any parts, but the parts were very nice. The M2 Intercoolers were ASP designs.

how big of piping?

Its all 3" SS piping and muffler. I have a Borla XR1 with a 4.5" tip on instead of the Dynomax that was originally used (WAY TO LOUD)

dynomax haaha:D yea im sure that didnt last long, probably blew to shit in a few months eh?

The muffler it self was very nice quality. All SS, problem was it was so freaking loud! Just see how long it takes the cops to pull you over. Its a much more mellow tone now.
