GMC Sierra 1500 Performance Exhaust - Flowmaster American Thunder Cat-Back (2007-2013). This bolt-on system delivers a deep, moderately aggressive tone and dependable Flowmaster performance for your truck.
Designed for the 5.3L Sierra 1500 (also compatible with select Silverado models), this emissions-legal cat-back uses 3.00-inch mandrel-bent stainless steel tubing feeding a Super 40 Series muffler with Delta Flow Technology. Mandrel-bent 2.50-inch tailpipes allow exits straight out the back or behind the rear tires—great when towing. Large 3.50-inch double-wall polished tips complete the setup. Stainless construction, included hardware, and dyno-tuned performance help make installation straightforward. Fits 2WD/4WD with 143.5 or 157.5-inch wheelbases; also fits 2007-2008 4.8L with the same wheelbases.
