Description

The Black Elite Series by Gibson offers a T-304 stainless tip with a premium black finish. This Single Side Exhaust improves acceleration, hill climbing, towing, and passing power, exiting behind the rear tire. It's designed to be quieter in the cab than other performance exhausts, delivering maximum torque and horsepower at low-end (1800-3000 RPM). Dyno tests show average gains of 10-15 HP and 15-20 lb-ft of torque. It features a hassle-free, bolt-on installation with factory-style hangers and no welding required. Made in the USA and backed by a Lifetime Limited Warranty.
