then the cat-back wont help you much. headers will. cat-back only changes sound and you could do that alot cheaper with some mufflers.
how much are you looking to spend and how fast do you want to go? just please dont tell me you want to spend $1000 and run 12s, you cant do it unless you just spray the crap out of the car.
So Bio, I got $800 and want to run 11's.
Can I do it?:th_tongue2:
LOL
ummm im waiting to sell my family property and im going to be left with like 10 grand so i was thinking on a zzp engine because mine is possibly cracked. i plan on getting everything new, i really want to make it the best gtp i can
Then get a set of diamond pistons, Intense Stage 4 heads and Stage 4 Cam, L32 rods, Whipple W140AX & 3.5" pulley, Stage 3 Intercooler, 60# Injectors, ZZP Headers, HP Tuners, ZZP Billet Throttle Body, and a Triple Edge Performance Transmission with whatever gears you want, Bulletproof Input Shafts and everything else Dave offers that is top notch. With all those mods and slicks I would not be surprised if you hit low 11's or high 10's.
