Hi all. I drive a 2003 GMC Sierra with the 4.8 liter and an auto tranny. Site looks pretty awesome! I actually came because I've been experiecing some problems with it but I'll get to that later. For now here are a few pics of what I have and also my mods list:

Flowmaster 40 Series muffler with duals out the passanger side in front of the back tire.
Trans Dapt Torque Curve throttle body spacer.
Red neck ram air mod with K&N drop in air filter.









Lemme know what you guys think. Plans(if I keep it) are to lower it and get some much wider wheels on there. I want it to look like it's ready for the track. Was thinking a 3/4 drop, roll pan(not sure yet), and something Corvettish for wheels.
