thanks.. i had my exhaust made but i haven't got around to installing it yet.. i have the y-pipe and rear section installed but not the rest of the pipeing.. i new it would hurt me so thats why it's not installed. I will be running around a 75 shot on top of it.. i might just do intake and the rest of my exhaust maybe headers.. some weight reduction and call it a day.. any guesses whay i would trap with a 75 shot and bolt ons? I would love to trap around 103-105 on n20... is this possible?
