RB header 2 Corksport Exhuast
 

ok i have a racing beat header and the corksport catback...not the one that fits to stock cat...does anyone know how big of a test pipe im going to have to make or has anyone made one?:confused:

anyone?

...ever heard of a tape measure??

i have a corksport exhaust, no header yet though, and i have "36 of striaght pipe (with a cat in it) between the catback flange, and a bend that goes up to the stock manifold. bend is about 8 inches... i've put on a RB header in my friends car, and it was pretty close to there, so i'd say a little less than "36 inches...
