Does anyone have any experience with Banks PowerPack System? They claim 25 rwhp and 26 rwlb-ft gains with no mention of premium gas. I have no idea how much it cost, but it consist of stainless steel headers and a stainless cat-back exhaust system and an air filter housing with a K&N type filter.

My dad's business partner has one on his Suburban and loves it. I'm pretty sure the package included an OBD retune too.

Not 100% sure on the cost, but I think it ran around $2K for everything (headers, cat-back, retune, air intake and the big Banks Power logos on the rear and sides).

 

What is an OBD retune?

$2000 seems like a lot of money for headers, exhaust, and an airbox with filter.
