Big torque for low price
This cat back was a small struggle to line up with aftermarket headers, but the sound and mid range torque is great. There is no interior drone and is pleasant for a daily driver.

Gibson Single Side Exhaust is perfect for improved acceleration, maximum hill climbing, towing and passing power. This is our best performing Exhaust System. Exits behind the rear tire. Quieter in the cab than any other Performance Exhaust. Dyno test results show it makes maximum torque and horsepower at low-end (1800 to 3000 RPM). Horsepower gains average 10-15 and 15-20lb-ft of increase torque. Hassle free, bolt-on installation with professional looking results. No welding required. Backed by a Lifetime Limited Warranty.
