Gibson 11-19 GMC Sierra 2500 HD Denali 6.0L 3.5in/3in Cat-Back Dual Extreme Exhaust - Black Elite

This Gibson Black Elite cat-back exhaust system is built for the 2011-2019 Chevrolet Silverado 2500 HD and GMC Sierra 2500 HD models equipped with the 6.0L engine. It features 3.5-inch inlet and 3-inch dual outlet piping, designed to exit aggressively behind the rear tires. The system is constructed from T-304 stainless steel tubing, known for its resistance to corrosion, and is finished with Gibson's exclusive black coating for a bold street appearance.

At the heart of this system is Gibson's Superflow muffler, which uses a baffled and chambered design without internal packing to produce a vigorous, deep exhaust tone. This design has been dyno-tuned and tested to achieve street performance gains. The bolt-on installation is made straightforward with included hardware and factory-style hangers, meaning no welding is required. This well-built system aims to provide both a powerful sound and a distinctive look for your truck.

Gibson backs this Black Elite exhaust with a limited lifetime warranty, reflecting their commitment to quality and durability. The system is proudly made in the USA, ensuring a high standard of manufacturing. While it delivers an aggressive sound, Gibson has engineered it to minimize interior drone, making it a comfortable option for daily driving and longer trips.
