Gibson 315535 Cat-Back Single Exhaust System Aluminized Steel with Slash-Cut Tip

The Gibson 315535 Cat-Back Single Exhaust System is a bolt-on performance upgrade engineered for trucks and SUVs that demand more power, a deeper exhaust note, and quieter in-cab driving comfort. Exiting behind the rear tire, this aluminized steel system is dyno-tested to maximize torque and horsepower in the critical low-end RPM range of 1,800 to 3,000 RPM — ideal for acceleration, hill climbing, towing, and passing.

• Aluminized steel mandrel-bent tubing for smooth, unrestricted exhaust flow and corrosion resistance
