Gibson 11-19 GMC Sierra 2500 HD Denali 6.0L 3.5in Cat-Back Single Exhaust - Black Elite

If you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a more commanding presence, this Gibson Black Elite Series cat-back exhaust system is a solid choice. It's designed to replace your factory exhaust from the catalytic converter back, giving your truck a deeper, more aggressive sound and improved exhaust flow. This system is specifically tuned for the 6.0L engine, aiming for that vigorous deep tone without excessive interior drone.

What sets the Black Elite Series apart is the T-304 stainless steel tip, finished with Gibson's exclusive black coating. The tubing itself is also made from high-quality stainless steel, mandrel-bent to ensure consistent diameter and smooth airflow throughout the system. Inside, you'll find Gibson's Superflow CFT muffler, which uses a baffled and chambered design with no internal packing. This construction helps achieve that powerful sound while minimizing interior noise, so you can enjoy the rumble without it being overwhelming on the highway. The kit includes all the necessary hardware and factory-style hangers for a straightforward bolt-on installation, meaning no welding or cutting is typically required.

Beyond the sound and style, this Gibson exhaust is engineered to provide a noticeable bump in performance. You can expect an estimated gain of 10-15 horsepower and 15-20 lb-ft of torque, thanks to the improved exhaust flow. Gibson backs this system with a limited lifetime warranty on the stainless steel components, reflecting their commitment to quality and durability. This system is made in the USA, ensuring you're getting a well-built product designed for long-lasting performance and a distinctive look.
