Gibson 11-13 GMC Sierra 1500 Denali 6.2L 3.5in Cat-Back Single Exhaust - Stainless

If you're looking to get more out of your 2011-2013 Chevrolet Silverado 1500 Denali with the 6.2L engine, this Gibson cat-back exhaust system is a solid choice. It's designed to bolt right onto your truck, giving you a noticeable improvement in acceleration, hill climbing, and towing power. The system exits behind the rear tire with a single polished stainless steel slash-cut tip, offering a clean look and an aggressive sound that's still quiet inside the cab.

Gibson's Superflow muffler uses a baffled and chambered design, which helps reduce interior drone while still allowing for better exhaust flow. Dyno tests show this system makes its best torque and horsepower gains between 1800 and 3000 RPM, with an average increase of 10-15 horsepower and 15-20 lb-ft of torque. The tubing is made from polished stainless steel and is mandrel-bent to ensure smooth airflow. Installation is straightforward, using factory-style hangers and the included hardware, meaning no welding is required.

This Gibson exhaust system comes with a lifetime limited warranty, reflecting its well-built construction. It's a complete cat-back system, meaning it replaces the factory exhaust from the catalytic converter back, offering a hassle-free installation for a professional look and improved performance.
