This is my 2005 GMC Sierra 1500 RST Regency. It has the 4.8 Vortec V8 and a 5-speed trans. The truck came from Regency with a Trick Flow intake, JBA plug wires, JBA headers, and a Powerflow exhaust that has been replaced with a Flowmaster exhaust. Supposed to push out about 300hp. Outside the Regency has a billit grill, red stripes, a tail gate spoiler, steel roll pan with exhaust cut outs, special exaust tips, and 20" wheels with 275/45/20 tires. Inside it has special RST Regency leather seats, special shifter, RST guages, and a carbon fiber dash.
