What ONE Mod Boost HP The Most?
i'm just curious... kinda trying to make a decision on what to do first to up the power on my soon arriving box. i have intake and exhaust all ready, so what will it be?

Well a header exhaust and a CAI is enough to make you add a new clutch down the road. I know of a xB that needed a new clutch just from an intake and an exhaust. The stock clutch can't take very much.
Injen short ram is probably going to be your best bet for the money.

yeah why short and not cold air?
possibly because longer cold air should bring torque up due to longer tubing, and since he wants HP the shorter ram air should bring the power curve closer towards the top end, i dunno??
personaly, torque is the only measurement i would care about, its what moves the car. but thats just me

i did the muffler then header then injen sri
i really felt the free'ed up power on the muffler and header when i did the sri imho that was really for the sounds i didn't feel any increase in free'ed up power (with my butt dyno that is)
