06's are nice, definately look into an addative of some sort deezol, diesel power whatever you can get for a good price.
Banks stuff is way over priced and under powered compared to everything else on the market. Plus they want you to buy their "bundle" or waste of parts. Get an AFE air intake system, cut out the cat and muffler, throw in an MBRP muffler or something similar and a strait pipe to replace the cat, you already have a 4" exhaust system stock you dont need a whole new system. The stock intercooler will be fine and their high ram is a waste of money.
