DPF-Back Exhaust Systems

Upgrade your diesel truck’s exhaust flow, reduce exhaust gas temperatures (EGTs), and improve rear-end styling with emissions-compliant DPF-back exhaust systems. Connecting directly downstream of your factory Diesel Particulate Filter (DPF), a DPF-back system replaces the restrictive rear tailpipe section, over-axle pipe, and OEM muffler or resonator without altering required emissions control equipment or triggering check engine lights.

Whether you're towing heavy loads, seeking a deeper exhaust tone, or upgrading to large-diameter single or dual exit exhaust tips, a DPF-back exhaust provides a 50-state legal performance upgrade that maintains factory warranty compliance. Explore mandrel-bent T304 stainless steel, T409 stainless steel, and heavy-gauge aluminized steel DPF-back kits in 4-inch, 5-inch, and dual pipe configurations. Featuring high-flow mufflers or muffler delete designs with polished, black powder-coated, or carbon fiber tips, find direct bolt-on systems engineered for Ford Powerstroke, GM Duramax, RAM Cummins, and Nissan Titan diesel trucks.
