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

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.

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.

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)

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.
