Large, 3 mandrel-bent 409 stainless steel tubing outflows the restrictive OE exhaust to increase horsepower and torque. In testing, the Rock Basher cat-back system resulted in gains up to +9 horsepower and +8 lbs. x ft. of torque, as measured on our in-house dyno. This exhaust delivers the performance gains you expect, and the signature engineered sound of aFe POWER. This cat-back exhaust system has a turn-down tip under the vehicle, before the rear axle, producing a signature exhaust tone. A free-flowing stainless steel muffler is used to absorb high pitch tones producing a powerful sound and unleashing all available horsepower and torque. This exhaust system uses all factory mounting locations, and high quality hardware for a 360-degree sealing surface and hassle-free installation. OE-style bayonet hangers are used to maintain a stable pipe location during high vibration and high heat conditions. The Bayonet tip holds the hanger bushing in place for an OE style fit that does not change with time.
