Hey guys I have a really good deal from a friend parting with his Berk (63mm) tp. I have an Invidia V3 (70mm) exhaust. I don't think it should cause any problems as its going from a smaller diam to a larger one. Someone correct me if I'm wrong .

If you have a 70mm exhaust I'd go ahead and get a 70mm TP as well.

Got a 63mm invidia, gained +7hp on the dyno. Paired with my 63mm apexi exhaust and Injen cold air. Got more power, better sound and no more drone.

I had a Test-pipe on my AP1 when i had it and, i couldnt stand the fuel smell. Do the high-flow cats have any less of a fuel smell or, are they just as bad?

Has anyone found a company that makes a high flow cat for an 06 to present s2k?

Berk advertises that their HFC is for 00-08. Thats the only one I really know of

I want to buy the skunk mega power exhaust and the ad says its 60mm piping. Their test pipe is 70mm so is this an ok set up or does it hurt to drop the sizing with the megapower after the test? i wanna try to stay with one company on my exhaust and i figured that if skunk made them different sizes that it would be for a reason but i wanna make sure with you guys before i go and spend 700+ dollars for the parts.

does anyone kno the diameter of the buddy club prospec III exhaust so i can get tp to match?

The Skunk2 test pipe is 70mm and their exhaust is 70mm into 60mm at the split. That's what you were referring to.

Mrwilliams

if i have the stock exhaust would getting a 70mm TP be worth it? or am i better off going 60mm
