Gibson 15-19 GMC Sierra 2500 HD Base 6.0L 3.5in/3in Cat-Back Dual Extreme Exhaust - Stainless

If you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a more aggressive sound and a noticeable performance boost, this Gibson Dual Extreme cat-back exhaust system is a solid choice. Designed for the 6.0L engine, this system replaces your factory exhaust from the catalytic converter back, exiting behind the rear tires with a bold, angled stance. It's built to deliver a powerful exhaust tone that commands attention on the street.

This system is constructed from durable stainless steel, featuring mandrel-bent tubing for smooth exhaust flow. The heart of the system is Gibson's Superflow CFT muffler, which uses baffles and chambers instead of internal packing to create a mean performance sound while minimizing interior drone. You can expect an improved exhaust note and dyno-tested performance gains, typically in the range of 15-20 horsepower. The package includes polished stainless steel slash-cut tips that clamp on, adding a sharp visual element to your truck's rear end.

Installation is straightforward thanks to the bolt-on design, meaning no welding is required. All necessary hardware and factory-style hangers are included to make the process as hassle-free as possible. Gibson backs this system with a Lifetime Limited Warranty, giving you confidence in its longevity and performance.
