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

Gibson is known for building well-made exhaust systems that offer a noticeable improvement in sound and performance. If you're looking to give your 2011-2019 Chevrolet Silverado 2500 HD or GMC Sierra 2500 HD a more aggressive exhaust note and a bolder look, this Dual Extreme Cat-Back system is a solid option. It's designed to fit behind the rear tires, giving your truck a powerful stance and a commanding exhaust tone that’s tuned for street performance.

This system features 3-inch mandrel-bent stainless steel tubing for smooth exhaust flow, which Gibson dyno-tunes to achieve average horsepower gains of 15-20. The heart of the system is the Superflow™ CFT muffler, which is baffled and chambered without internal packing, contributing to its aggressive sound while minimizing interior drone. The system includes polished stainless steel slash-cut tips that clamp on for a clean finish. Installation is straightforward thanks to the bolt-on design, meaning no welding is required, and it uses factory-style hangers for a secure fit.

This Dual Extreme exhaust system comes with all the necessary hardware for installation and is backed by Gibson's Lifetime Limited Warranty, giving you confidence in its durability. It's a complete package for those who want an extreme exhaust upgrade for their heavy-duty truck.
