Gibson 07-09 GMC Sierra 1500 Denali 6.2L 3in Cat-Back Dual Extreme Exhaust - Stainless

If you're looking to give your 2007-2009 GMC Sierra 1500 Denali with the 6.2L engine a serious performance upgrade, this Gibson cat-back exhaust system is built for that purpose. This dual exhaust system exits behind the rear tires at an aggressive angle, giving your truck a bold look and a powerful exhaust tone that lets everyone know you mean business. It's designed to complement the Denali's style while adding a noticeable performance edge.

Gibson has engineered this system with their Superflow™ CFT muffler, which uses baffles and chambers instead of internal packing to create a mean performance sound. Despite its aggressive tone, it's tuned to minimize interior drone, so your cabin stays comfortable on longer drives. The tubing is made from stainless steel and is mandrel-bent to ensure smooth exhaust flow, which helps contribute to the dyno-tested performance gains of an estimated 15-20 horsepower. The system is finished off with polished stainless steel slash-cut tips that clamp on for a clean look.

Installation is straightforward thanks to the bolt-on design, meaning no welding is required, and it uses factory-style hangers for a secure fit. All the necessary hardware is included to get you up and running. Gibson backs this system with a Lifetime Limited Warranty, reflecting their confidence in the durability and performance of this stainless steel exhaust.
