Nice truck! I wasn't a silver fan until this new silver came out. It really looks sick with a set of black wheels on it. I didn't get it because I already made a deal on a Tungsten. I really like the 14s, they drive like a cadillac. I have been debating on doing the same as you, exhaust and intake. the only thing I have done is wheels, 2in rear drop and tint. I have been reading on another GM site that has a bunch of 14s talk on it. Magna flow is what most of the members are running. When I do it that is what i'm going with. Here is my truck.
