Boost Diesel Performance with DPF Back Exhaust Systems
Upgrade your diesel vehicle's sound, appearance, and exhaust efficiency with high quality DPF back exhaust systems. Designed to replace the factory system downstream of the Diesel Particulate Filter (DPF), these systems provide better flow, reduce restriction, and enhance exhaust tone without altering emissions components or compromising compliance.

Our selection includes stainless and aluminized steel DPF back kits in a variety of diameters, tip styles, and configurations to match trucks, work vehicles, and tow rigs. With mandrel bent tubing and larger diameter piping, these systems help reduce backpressure and improve airflow, especially under load or during towing. Many options are direct fit for easy installation and come complete with clamps, hangers, and hardware.

Ideal for diesel drivers looking for a performance edge while staying emissions friendly, DPF back systems deliver a noticeable upgrade in tone, appearance, and efficiency. Explore durable kits that bring out the best in your diesel build.

Frequently Asked Questions

DPF-back means the system replaces exhaust components downstream of the diesel particulate filter on compatible diesel vehicles. It is designed to leave the factory DPF and upstream emissions equipment in place. Match the system to the exact truck, engine, wheelbase, and factory exhaust configuration because diesel exhaust layouts can vary significantly.

No. A true DPF-back system begins after the diesel particulate filter and is intended to retain that emissions component. If a product requires removal or defeat of factory emissions equipment, it is not the same type of upgrade. Use the manufacturer application and installation instructions to confirm what factory components remain in place.

Match the exact year, make, model, engine, cab and bed or wheelbase configuration when the manufacturer calls them out. Also compare outlet style, pipe diameter, material, and whether the kit is designed around the factory hitch, spare tire, suspension, and emissions equipment. Vehicle-specific fitment matters more than choosing by pipe size alone.

Inspect the factory connection behind the DPF, clamps, hangers, isolators, and the existing tailpipe for corrosion or damage. Check the kit contents to see which factory pieces are reused. Replacing worn clamps or hanger isolators while the system is apart can make the installation cleaner and help prevent leaks or rattles.
