Product Details

The Gibson 65516 Cat-Back Super Truck Exhaust System is engineered for truck enthusiasts who demand an aggressive race-inspired sound and measurable performance gains. Featuring a dual outlet design with tailpipes that exit in front of the rear tires, this cat-back system delivers a deep, powerful race rumble tone straight from the factory—no welding, no fabrication required.

Gibson's exhaust systems are dyno-tested to reduce backpressure and improve exhaust flow, with typical gains of 10–15 horsepower and 15–20 lb-ft of torque. The system includes mandrel-bent stainless steel tubing, a high-flow SuperFlow muffler, polished sport tips, and all necessary mounting hardware for a complete bolt-on installation.
