'99 GT Vert HP gains with a MAC setup..
Noob here...
I need to know what kind of RWHP gains I can get with an 2.5" H-pipe, 2.5" Cat-back Exhaust, CAI all MAC and a Hypertech Programmer III.
Tried the same post in the 4.6 forum with not much luck. I just want to see if it's worth doing over having the neighbors whine and cops following me all over.
