Product Details

The Gibson 65204 Dual Sport Cat-Back Exhaust System is engineered for trucks and SUVs that need a clean, functional dual-exit setup. Routing exhaust outlets behind the rear tires keeps your tow trailer clear of exhaust gases while giving your vehicle a distinctive, aggressive street or off-road look. The system is fully bolt-on with no welding required, delivering professional-quality results with a straightforward installation.

Dyno-tested for real-world performance, this system delivers average gains of 10–15 horsepower and 15–20 lb-ft of torque, while the baffled and chambered muffler design produces a deep, authoritative exhaust note with minimal interior drone. Backed by Gibson's Lifetime Limited Warranty.
