Description

Our American Thunder cat-back exhaust system for 2007-2013 GM Silverado/Sierra 1500 with the 5.3L engine, is perfect for the person looking for moderately aggressive sound levels both inside and outside of the truck. This bolt-on emissions-legal system features 3.00-inch mandrel-bent stainless steel tubing flowing into a Super 40 Series muffler, for a deep powerful sound.

The mandrel-bent 2.50-inch stainless steel tailpipes can be configured with your choice of exit locations, either straight out the back under the bumper for a muscular look, or exiting out behind the rear tires on each side of the truck. This is the ideal tailpipe location when towing a boat or RV. The tailpipes are finished off with large 3.50-inch double wall polished stainless steel tips. The system includes all necessary parts and hardware for an easy installation and is covered by our Lifetime Limited Warranty. Notes: Fits all 2/4 wheel drives with 143.5 and 157.5-inch wheelbases. Also fits 2007-2008 GM Silverado/Sierra 1500 with 4.8L engines and 143.5 and 157.5-inch wheelbases.

  • Stainless Steel Construction
  • Lifetime Limited Warranty
