Gibson 65619 Cat-Back Dual Sport Exhaust System Stainless Steel

The Gibson Performance 65619 Dual Sport Cat-Back Exhaust System is engineered for truck and SUV owners who want a clean, rear-tire exit that keeps the exhaust path clear when towing. Built with 2.50-inch stainless mandrel-bent tubing, this system maximizes exhaust flow and minimizes backpressure for real, measurable performance gains.

Gibson's dyno-tested design delivers average gains of 10–15 horsepower and 15–20 lb-ft of torque, concentrated in the low-end RPM range where trucks and SUVs need it most. The baffled and chambered muffler produces a deep, aggressive exhaust tone while keeping interior drone to an absolute minimum — no annoying cabin resonance on the highway.
