i've got an 02 5.3 sierra and i am looking for exhaust tips. i want to run Lt headers but dont know witch way to go. Also i want to install a procharger but i never see any talk of them on here. is there a reason?

From what I've seen most of the guys in here that are running FI are either running the STS turbo kit or the Radix blower. Someone should come a long and chime in about the procharger, I don't really know much about it. As for LT's, the popular ones are Pacesetter, Dynamaxx, Stainless Works, ASM, umm...drawing a blank...did I forget any? It makes a difference if you have 4wd or 2wd...some don't fit 4wd.

People that are running the prochargers are running a little more power, so there are a few of them, there are more radix people, because they offer a complete kit. Prochargers are not complete.

what else does the procharger kit require
