long tube headers for one

I'd say internals and the long tubes. Seems like you pretty much have the rest covered.

Forged internals FTW!You're like pieces away from completingyour puzzle!Internals, LT's, and a few other parts and I dont see why you shouldnt be able to hit 550rwhp! But just go with the internals+ a bit more for install and then save up for the LT's!
