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

If you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a more aggressive sound and a bolder look, this Gibson Dual Extreme cat-back exhaust system is a solid choice. This system is designed to bolt directly onto your truck, replacing the factory exhaust from the catalytic converter back. It features 3.5-inch diameter tubing that steps down to 3-inch, exiting through dual polished stainless steel slash-cut tips positioned aggressively behind the rear tires. The goal here is a powerful exhaust tone that announces your truck's presence without excessive interior drone, thanks to Gibson's Superflow CFT muffler which uses baffles and chambers instead of internal packing.

Gibson tunes and tests these systems to help achieve noticeable performance gains, with many users reporting an average increase of 15-20 horsepower. The aluminized steel construction offers good durability for everyday use, and the polished stainless steel tips add a sharp visual accent. Installation is designed to be straightforward, utilizing factory-style hangers and including all the necessary hardware, meaning no welding is required. This makes it a popular option for those who want to upgrade their truck's exhaust system themselves.

This system is backed by Gibson's Lifetime Limited Warranty, giving you confidence in its longevity. It's a comprehensive package for anyone seeking an extreme exhaust upgrade for their heavy-duty Silverado or Sierra.
