Flowmaster - 07-13 Gm P/U 5.3L A/T Exhaust Kit

The Flowmaster American Thunder Cat-Back Exhaust System is designed for 2007-2013 GM Silverado/Sierra 1500 trucks equipped with the 5.3L engine. This bolt-on, emissions-legal system features 3.00-inch mandrel-bent stainless steel tubing that channels exhaust flow into a Super 40 Series muffler, delivering a deep, powerful sound. The 2.50-inch stainless steel tailpipes can be configured for either straight-out-the-back or side exits behind the rear tires, providing flexibility based on your preference or towing needs. The system is finished with large 3.50-inch double-wall polished stainless steel tips for a sleek appearance. Installation is straightforward with all necessary parts and hardware included, and the system is backed by Flowmaster's Lifetime Limited Warranty. Compatible with both 2-wheel and 4-wheel drives featuring 143.5 and 157.5-inch wheelbases, it also fits 2007-2008 GM Silverado/Sierra 1500 models equipped with 4.8L engines and the specified wheelbases.
