Gibson Performance 315530 Swept Side Cat-Back Single Exhaust System Aluminized

The Gibson Performance 315530 Swept Side Cat-Back Single Exhaust System is engineered to deliver real-world horsepower and torque gains right where you need them most. Dyno-tested to maximize power output in the 1,800–3,000 RPM range, this cat-back system is purpose-built for everyday driving demands including towing, hauling, hill climbing, and passing. Average gains of 10–15 horsepower and 15–20 lb-ft of torque make this one of Gibson's top-performing exhaust solutions. The single side exit routes behind the rear tire for a clean, factory-integrated look with a distinctly aggressive exhaust note.

Constructed from aluminized mandrel-bent steel tubing, this system uses a slip-fit joint design that minimizes turbulence and reduces power-robbing backpressure. The all-welded, baffled and chambered Superflow™ muffler delivers an aggressive sound with minimal interior drone — keeping cabin noise refined while still announcing its presence outside the vehicle. A polished T304 stainless steel 3.5-inch round slash-cut tip adds a premium finishing touch.
