aFe Rock Basher Exhaust Systems

The aFe Rock Basher exhaust systems are durable, purpose-built cat-backs for the 2018 Jeep Wrangler JL. They improve clearance over rough terrain for the adventurist who wants it all. The large 3 in. mandrel-bent 409 stainless steel tubing outflows restrictive factory exhausts, delivering gains of up to 9 hp and 8 lbs.-ft. of torque, as measured on aFe's in-house dyno. The free-flowing muffler delivers a power performance tone, while the Rock Basher's unique pre-axle turn-down tip handles off-road obstacles. These exhaust systems utilize factory mounts for a quick and easy install.
