Product Details

The Gibson 615587 Cat-Back Single Exhaust System is engineered for drivers who demand real performance gains without sacrificing drivability. Designed to exit behind the rear tire, this single-side system delivers a quieter in-cab experience compared to other performance exhausts while still producing an aggressive tone under load. Dyno-tested results demonstrate maximum torque and horsepower gains concentrated in the critical low-end RPM range of 1,800 to 3,000 RPM, where towing, hauling, and passing power matter most. Expect average gains of 10–15 HP and 15–20 lb-ft of torque.

The system features a baffled and chambered muffler design with no internal packing material, minimizing interior drone while maintaining an aggressive exhaust note. Installation is fully bolt-on with no welding required, delivering a clean, professional-looking result. Backed by Gibson's Lifetime Limited Warranty.
