  • Delete pipe: bolts on with the bolts and clamps we provide. No welding, just basic tools you probably already own, like wrenches and ratchets.

CAB & CHASSIS INFORMATION

These pipes are designed for pickup models. Cab & Chassis trucks will need modifications for the pipe to fit.

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.

Nice fit, poor tech support

Pipes were all bent for a perfect fit. Tail pipe had one ding in it which was probably damaged in shipping and easily pounded out for a proper fit. Hangers all matched up really well. The diesel dude’s technician told me to reuse the OEM gasket and studs. The gasket was not reusable but only cost me $13.00 at the auto store. The studs were easily pounded out with a dead blow hammer but didn’t fit the holes in the new pipe. Overall I would give the pipes a 10 and the technicians help useless because the gasket should not be reused and the diameter of the OEM studs were too small to seat in the flange of the new pipe. Put one together before giving advice. A note to the technician, reverse the studs, use a washer/ lock washer and nut on the new pipe side. Tell the customer to purchase a new gasket before starting the job. This saves the customer frustration and time running out to the store in the middle of the job.

4 inch exhaust

Truck sounds good, doesn’t drone, little louder at idle than what I expected, but these engines are noisy, so unless you put a 5 foot long school bus muffler on it’s going to be loud. Install was very easy.
