The 4" Full Exhaust DPF Delete for the 2019-2024 Ram 6.7 Cummins removes the Diesel Particulate Filter (DPF) and catalytic converter (CAT) from your Ram 2500 or 3500, ending forced regen cycles, cutting backpressure, and letting your Cummins work the way it was built.

The factory DPF forces regen cycles that waste fuel, add heat, and interrupt your work, usually at the worst times: under load, towing, or out on the highway. A 4" delete exhaust removes the restriction entirely. Without that backpressure your Cummins breathes freely, EGTs drop under heavy loads, and fuel economy improves noticeably.

This is a downpipe-back system in high-quality aluminized steel that replaces the factory DPF and CAT with a straight, free-flowing pipe. OEM-style hangers and clamps lock it in the same way the factory exhaust did, so the fit is clean and rattle-free with no welding.

In the box you get the 4" aluminized steel full exhaust, the OEM-style hangers and clamps, and a step-by-step installation guide. It fits all cab and box lengths, including HD models, but does not fit Cab & Chassis trucks or 2018-and-earlier 6.7L Cummins engines.

You'll need a compatible delete tune to keep DPF-related check engine codes from setting, so call (888) 830-2588 and we'll pair the right tuner to your 2019-2024 Ram. Free shipping is included, with standard delivery in 8-10 business days and express available at 5-8.

Exhaust systems are a final sale, but if your system arrives damaged or we ship the wrong product, we'll send a replacement at no cost. Tech support is included and tickets are answered within one business day.

For off-road/competition use only.
