Product Details

The Gibson 316516 Cat-Back Single Exhaust System is an aluminized, bolt-on performance exhaust designed to maximize low-end torque and horsepower. Engineered for drivers who demand improved acceleration, enhanced towing capability, and stronger passing power, this system exits behind the rear tire for a clean, factory-integrated look. Dyno testing confirms peak power gains are delivered in the critical 1800–3000 RPM range, with average increases of 10–15 horsepower and 15–20 lb-ft of torque.

The baffled and chambered muffler design eliminates internal packing for long-term durability while keeping interior drone to a minimum — delivering an aggressive exhaust note that remains quieter in the cab than competing performance systems. No welding is required; this is a 100% bolt-on installation with professional-quality results.
