Well, anyways. I have an 07 Silverado WT Reg Cab SWB with a 4.8. I decided to start playing around with it and here's my progress so far... So far, it has true dual exhaust with 2ch flowmaster 40 series mufflers, hypertech power programmer III, and a Volant CAI. I decided to start working on the outside, getting away from the work truck look. Here's a couple of pics from this morning, replacing my bumper end caps with new ones loaded with TYC fogs. looks so much better with the painted bumper caps. more pics tomorrow Near future plans include long tube headers, 3.73 gears, 3/5 drop, 20" black wheels, and possibly flat black racing stripes.
