Engineered for hard-core off-road use only, this cat-back system has your JK’s ground clearance and suspension articulation in the forefront of its design. With a mid-body exhaust dump position, the Evolution Competition System is tucked away inside the frame rails of the vehicle for optimal clearance as well as functionality with other aftermarket suspension systems and frame/body protection accessories.
