Product Details

The Gibson 615570 Cat-Back Single Side Exhaust System is engineered for maximum performance gains across the powerband, making it an ideal upgrade for drivers who demand stronger acceleration, improved towing capacity, and confident passing power. Featuring a rear exit behind the rear tire, this system delivers a more aggressive exhaust note while remaining noticeably quieter inside the cab compared to competing performance exhaust systems.

Dyno-tested results demonstrate peak torque and horsepower gains concentrated in the low-end RPM range (1,800–3,000 RPM), with average increases of 10–15 horsepower and 15–20 lb-ft of torque. The bolt-on design requires no welding and installs with professional-quality results right out of the box. Backed by Gibson's Lifetime Limited Warranty.
