im not sure if i would call a heads, cam, and kb at 10 psi mild lol well mabye when you compare it to other larger forced induction cars, but anyways im sure the longtubes would be well worth it with that set up.

LOL that is mild. I guess you consider a CAI mild? lol

anyways, do you have any headers on there now or are they stock manifolds? If you have stock manifolds your answer is about as plain as your nose on your face. If you are considering changing from a short to a full length header its still going to be worth it. Do it either way, but most definately do it if you only have stock manifolds.

Obviously a setup like that would benefit from LT headers.

anything ball and socket will make less power.
LT's, then equal shorts, then shorties, then stock.

Long tubes for sure. You will notice the differance as soon as you strap it to the Wrangler Dyno
