i have a 99 GTP with 171k miles on it i was thinking of doing the following:
Headers
3 inch cat-back Exhaust
3.6 inch pulley
FWI
Overkill PCM
along with the appropriate tsat spark plugs and s/c belt
would this damage my engine in any way, there would be some light racing as you can imagine and yes ive already read the safely modding your 3800 powered car thread
