Product Details
Gibson is known for making well-built 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 authoritative exhaust note while keeping things tidy, this Dual Sport Cat-Back system is a solid choice. It exits behind the rear tire, giving your truck a distinct look that stands out whether you're on the road or heading off it. Plus, the design ensures it won't interfere with your trailer while towing.
This system is constructed from stainless steel with mandrel-bent tubing, meaning the pipe diameter stays consistent throughout for better exhaust flow. The baffled and chambered muffler is designed to produce a powerful, deep exhaust tone that's aggressive outside the cab but minimizes annoying interior drone. Gibson's Superflow™ muffler technology is dyno-tested, showing average gains of 10-15 horsepower and 15-20 lb-ft of torque. Installation is straightforward thanks to a bolt-on design that uses factory-style hangers, so no welding is required for a professional-looking result.
Included with the system are polished stainless steel, slash-cut clamp-on tips that add a nice finishing touch. This cat-back exhaust comes with all the necessary hardware for installation. Gibson backs this system with a Lifetime Limited Warranty, giving you peace of mind with your purchase.
