Had any trouble finding races? That was the biggest issue I had with the Sierra and Silverado...both looked bone stock so even the ricers didn't think anything was up, had a hard time getting them to actually take off and race me. Exhaust was the last thing to be done to both, and afterwords it got much much better, lots more challenges by late 80s peice of crap Hondas with coffee cans for mufflers. It's amazing what those kids think their cars will do. It's got to be seriously embaressing to be out with your girlfriend and get flat out spanked by an early '90s full sized GMC in your super cool pimp car.
