The 4" Full Exhaust System for 2013–2018 Ram 6.7L Cummins removes the Diesel Particulate Filter (DPF) and Catalytic Converter (CAT) from your 2500 or 3500 — ending regen cycles, cutting backpressure, and letting your Cummins haul without the emissions system dragging it down.

The DPF forces regen cycles at the worst times: mid-tow, on the highway, when you're working. Every regen burns extra fuel at high EGTs, and the filter eventually clogs anyway. This 4" aluminized steel exhaust runs downpipe-back, replacing the OEM DPF and CAT sections with a straight, free-flowing pipe. Without that restriction your Cummins pulls cleaner, runs cooler under load, and stops burning fuel on filter maintenance. Most owners notice real fuel economy gains once the regens are gone.

It's built from high-quality aluminized steel with OEM-style hangers and clamps, so it bolts to factory locations across all cab and box lengths — no cutting, no welding. You get the full exhaust, the hangers and clamps, and a step-by-step installation guide. You'll also want a compatible delete tune to keep DPF codes away; call us at (888) 830-2588 and we'll match the right one for your year.

Fits 2013, 2014, 2015, 2016, 2017, and 2018 Ram 2500 and 3500 with the 6.7L Cummins — all pickup cab and box lengths. Does not fit Cab & Chassis, the 5.9L Cummins, or 2019+ trucks. Free shipping; standard delivery 8–10 business days. Exhaust systems are final sale, but damaged or wrong items get replaced free.

For off-road/competition use only.
