Product Details

The Gibson Performance 18805 Cat-Back Single Exhaust System is Gibson's top-performing aluminized exhaust solution, engineered to deliver maximum low-end torque and horsepower gains with a deep, aggressive exhaust tone. Dyno-tested to produce peak power gains in the 1800–3000 RPM range, this system averages 10–15 horsepower and 15–20 lb-ft of torque over stock — making it an ideal upgrade for towing, hill climbing, acceleration, and passing performance.

The system exits behind the rear tire and is specifically tuned to remain quieter inside the cab than competing performance exhausts, minimizing interior drone without sacrificing that signature aggressive sound outside.
