Gibson 2007 GMC Sierra 2500 HD Classic SL 6.0L 4in Cat-Back Single Exhaust - Stainless

If you're looking to get more out of your 2007 Chevrolet Silverado 2500 HD Classic, especially when towing or climbing hills, this Gibson cat-back exhaust system is a solid choice. It's designed to bolt right onto your truck, making installation straightforward without needing any welding. This system exits behind the rear tire, giving your truck a cleaner look and a more aggressive sound that's still comfortable inside the cab.

Gibson built this system using mandrel-bent stainless steel tubing, which helps maintain consistent exhaust flow and resists corrosion for a long life. The Superflow™ muffler is baffled and chambered, not packed, which is key to its performance gains and reduced interior drone. Dyno tests show this system really shines in the low-end RPM range, where you need it most for hauling and acceleration, with average gains of 10-15 horsepower and 15-20 lb-ft of torque. The polished stainless steel slash-cut tip adds a nice finishing touch.

This kit comes with all the necessary hardware and factory-style hangers to make the bolt-on installation as smooth as possible. Gibson backs this exhaust with a lifetime limited warranty, so you can be confident in its durability and performance for years to come.
