Gibson 619608 Cat-Back Single Side Exhaust System Stainless Steel

The Gibson 619608 Cat-Back Single Side Exhaust System is a bolt-on performance upgrade engineered for maximum low-end power delivery. Dyno-tested results demonstrate horsepower gains averaging 10–15 HP and torque increases of 15–20 lb-ft, with peak gains occurring in the critical 1,800–3,000 RPM range — ideal for towing, hauling, hill climbing, and passing.

The system exits behind the rear tire and is tuned to deliver an aggressive exhaust note while remaining noticeably quieter inside the cab compared to competing performance exhaust systems. No welding is required for installation, and all components are designed for a clean, professional fit using existing mounting points.
