Gibson 619655 Cat-Back Single Exhaust System Stainless Steel with Slash-Cut Tip

The Gibson 619655 Cat-Back Single Exhaust System is a bolt-on stainless steel performance exhaust designed to maximize low-end power where you need it most. Dyno-tested to deliver 10–15 horsepower gains and 15–20 lb-ft of additional torque in the 1,800–3,000 RPM range, this system is purpose-built for real-world performance including towing, hill climbing, acceleration, and passing power.

The system exits cleanly behind the rear tire near the factory location, providing a clean, factory-integrated look without compromising performance. Despite its aggressive exhaust note, the design keeps cabin noise levels lower than competing performance exhaust systems.
