You most likely gain HP but lose some torque.Misfit_Zero said:It's the truth, after installing my exhaust but before putting on my intake my car sounded like a muted version of what it is now... sounds much beefier than it did stock, but probably only bout 5-7 HP more than it was after all that work. and that's just what I'm assuming, it may even be at the same since I think the Intake lost a bit of HP from the elimination of that snorkel tube.
