Gibson 07-10 GMC Sierra 2500 HD SLE 6.0L 3.5in Cat-Back Single Exhaust - Stainless

The Gibson Cat-Back Performance Exhaust is a single, stainless steel exhaust system (MPN 615609) designed for 2007-2010 Chevrolet/GMC 2500HD/3500HD trucks equipped with a 6.0L engine. This system is engineered to enhance acceleration, towing, hill climbing, and passing power. It's considered Gibson's top-performing exhaust system, with dyno test results indicating maximum torque and horsepower gains at low-end RPMs (1800-3000 RPM), averaging 10-15 horsepower and 15-20 lb-ft of torque increase. The system features a Gibson Superflow Muffler with a baffled and chambered design, eliminating internal packing for minimal interior drone while delivering an aggressive sound. It exits behind the rear tire, maintaining a quieter cabin compared to other performance exhausts. Construction includes 3.5-inch 409 stainless steel mandrel-bent tubing and polished T304 stainless steel, slash-cut tips. Installation is a hassle-free, bolt-on process, requiring no welding, and includes all necessary hardware and factory-style hangers. The product is proudly Made in the USA and comes with a Lifetime Limited Warranty.
