Input On Mods.

[landmine]

I would like some input on some mods I want to do. My truck is a 2004 GMC Sierra ECSB 5.3 with 3.73 gears. Mostly I would like to know which make of these mods most of you would choose. I want to do a cat back exhaust, cai, electric fans, and maybe high flow cats and some headers. I know that I want a black bear tune but I figure it'll be better to wait until I do my other mods first. Almost forgot I want to upgrade my breaks too. Not bigger just better like slotted rotors and better pads. All input is appreciated.

You already have a high flow air intake & cats, so you can skip to the BB tune, electric fans and exhaust mods. You can actually do a true dual system that's much better than cat-back. And you can tell Justin what you plan to do if he gets to your area before you're finished and he can program accordingly.
