The Rock Basher is a durable cat-back exhaust system from aFe. It improves ground clearance making your Jeep overcome more off-road obstacles. The tubing is made from 409 stainless steel making it less restrictive to airflow than factory exhaust systems thus increasing engine performance with up to +9 horsepower and +8 lbs. x ft. of torque being produced. The 18" long free flowing muffler is made from stainless steel and produces a powerful tone to match the rugged off-road vehicle. The increased ground clearance is due to the turn down tip of the cat-back exhaust system just before the rear axle. Installation of the Rock Basher exhaust system is relatively easy because it uses factory exhaust mounting locations, which creates a snug fit and keeps the exhaust system in place even over rough terrain. The band clamps provide an all-round (360 degree) leak-free seal. Manufactured and engineered in aFe Corona, California facility in the U.S.

aFe - Advanced Flow Engineering Incorporated. They are manufacturers of aftermarket performance products for late model light trucks, SUVs, and cars. Founded in April 1999 with their concentration mostly on high performance air filters, due to the glaring need that there was lack of choice for an aftermarket high performance air filter.
