Open Cone is FTW...as long as your modded...its not the best idea for a stock car...maybe around a 3.4" setup...but its your call...open cone does give better throttle response and more blower whine...which is win.
Im pretty much stock why wouldnt you suggest?
I just wish the police loved my car as much as i do 3.5,160 Stat,HAI,ZZP F/R STB, SSAC Headers, Reptile PCM :
