This 4" Downpipe Back Exhaust starts at the downpipe and allows for the removal of the catalytic converter and DPF filter from the exhaust system for off-road use.
This race exhaust system is ideal for off-road enthusiasts who want to maximize their truck’s performance. The straight-pipe design enhances exhaust flow, reduces backpressure, and boosts fuel efficiency, giving your truck a noticeable performance edge.
*Does not fit the late models with the 3 bolt flange. Will not fit Cab & Chassis trucks.
