[QUOTE="broke7, post: 13247807, member: 9457"] My car made 744whp on a 2.8H thru some 1-5/8th MAC's, 2.5" Xpipe and Bullets. Here is something scary. I ditched the MAC's for my new build, before I sold them I measured the ID of the header collector and it was about 2.25-2.3" in most place. Not anywhere close to the 2.5" X-Pipe. After seeing that mess im pretty sure there is some power to be had which I will see with my new motor. The quickest twin screw combo in the land for 03/04's is using ARH 1-3/4 x 3" if that tells you anything. If these cars were choked out by "small" exhaust you would see it exploited way sooner. Then again I can remember making 690whp on my stock manifolds. [/QUOTE]
