Product Description

The aFe 49-48069 Rock Basher™ 409 SS Cat-Back Exhaust System is engineered specifically for 2007-2018 Jeep Wrangler JK 4-Door Unlimited models equipped with 3.6L and 3.8L V6 engines. Its large 3" mandrel-bent stainless steel tubing enhances exhaust flow compared with the stock system, helping support additional torque and horsepower while producing a deeper, more aggressive exhaust tone. The free-flowing 18" muffler minimizes backpressure and contributes to a powerful performance sound without excessive drone.

A standout feature of this system is the unique pre-axle turn-down exit, which routes the tailpipe forward of the rear axle to improve ground clearance and protect the exhaust tip from trail obstacles - a major benefit for off-road enthusiasts. Installation is straightforward with OE-style bayonet hangers and included quality clamps and hardware, providing a direct bolt-on fit without cutting or welding. This Rock Basher exhaust is ideal for Wrangler owners seeking enhanced sound, improved performance, and rugged construction tailored for adventuring on and off the trail.
