best #'s with Stock cat pipe

[brad65ford]

Well I've seen threads with best #'s and mod's which I'm into. But what about everthing else except the stock catted h pipe so that including (chip, pulley,headers,cat-backs,t/b's, and CAI's, etc..). Just want to see how restricting the stock mid cat pipe is:??:

JT (jtfx6552) ran an 11.7 @ 122 on the stock F1s with the stock H-pipe. CAI, 2.93, chip and Borla catback were his mods (and he's a hell of a driver).

Don't know what that translates into RWHP, but certainly proves that the stock H won't keep you out of the elevens...:thumbsup:
