sup guys, I'm building up my GSR but I need some advice on the exhaust system. I actually have CAI, skunk2 stage 1 cams, skunk2 intake manifold, cam gears, VAFC. I want to know what header (brand, 4-1 or 4-2-1, piping size) and full cat cat back exhaust(brand, and size) you suggest taking in consideration i'm not reving over 8100rpm.
thanks

Greddy 4-1 and Greddy Evo.

 

Dc 4-1, and Apex-i N-1 (it looks incredible...sounds awesome, and gives decent power gains)
