Gibson 11-19 Chevrolet Silverado 2500 HD LT 6.0L 3.5in Cat-Back Single Exhaust - Aluminized

This Gibson cat-back exhaust system, built with aluminized mandrel-bent tubing, is specifically designed for your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD. The 3.5-inch diameter tubing and Superflow muffler work together to improve acceleration, hill climbing, and towing power, especially noticeable in the low-end RPM range where you need it most for hauling or passing. You can expect an average gain of 10-15 horsepower and 15-20 lb-ft of torque, all while keeping interior noise to a minimum thanks to its baffled and chambered muffler design that avoids internal packing.

Installation is straightforward with a bolt-on design that uses factory-style hangers and includes all necessary hardware, meaning no welding is required for a professional-looking result. The system exits behind the rear tire for a clean look, and it's topped off with polished stainless steel slash-cut tips. This system is backed by a Lifetime Limited Warranty from Gibson, giving you peace of mind for years to come.
