Default Biggest TP To Fit Nismo Header &Y pipe

Hey, I was just wondering if any one knew what test pipe has the biggest diameter that will fit up to Nismo headers and a Nismo Y-Pipe? Also where can I find them? Any input would be great.

you also don't want to go w/ the "biggest"...you'd want something that's the same as your header and Y-pipe...increaseing the diamater might reduce the total flw resistance, but could significnalty lower your low end power.

I believe that the NISMO collector is 2.25 inches. So a 2.25 inch test pipe will be fine.

Damn, You would have thought Nismo would have designed a larger collector. Any one know how big the Nismo y pipe inside diameter is? I guess since thats the direction of the exhaust flow that would be the one that really matters.

I suggest you also replace Nismo y-pipe with better flowing y-pipe as well.
Nismo y-pipe sucks ***.
