So, i have a megan header that is 2.5 inches. I want a skunk 2 megapower which i believe is 60mm. What is the best way to connect everything. Or would looking for a 2.5 inch catback be a better idea? I'm not expecting it would matter to much either way, just looking for suggestions. Thanks and sorry for another exhaust question.

 

use a test pipe...i'm gonna be gettin 4 - 2 - 1 headers wit a 2.5 inch collector...gonna use a test pipe to fit that into a catback of a ws2...only problem is it's illegal and if ur caught u get fined...and secondly...the test pipe is a replacement part for your cat...so you will have no cat...now that means that come emissions test day, u gotta take off that exhaust system...and bolt on ur old one to pass it...then wen u get home, re dress it...thas what i'm gonna do...that is provided that u do keep ur old exhaust...but hope this helped
