The 5" DPF Delete Exhaust for 2019–2021 Ram 6.7 Cummins replaces the factory Diesel Particulate Filter and Catalytic Converter with a free-flowing 5" T-409 stainless steel pipe, ending the regen cycles, EGT spikes, and backpressure that hold these Cummins trucks back. It's the best-selling Dodge Ram 5" full exhaust.

The stock exhaust routes through a DPF that traps soot and burns it off in regen cycles that waste fuel and heat your engine right when you're pulling heavy loads. A 5" delete pipe removes that restriction permanently and lets your Cummins run like the workhorse it is.

The pipe connects at the down pipe outlet and runs full-length back to the tailpipe, replacing the DPF, CAT, and restricted mid-pipe sections with free-flowing 5" T-409 stainless that handles heat cycles without corroding. Without DPF backpressure your turbo builds boost faster, EGTs stay in check under tow, and removing the emissions system that has been suffocating your diesel can improve fuel economy. Avoiding one DPF replacement covers the cost of the pipe. You get the down-pipe-back exhaust, OEM-style hangers and clamps, all mounting hardware, and a step-by-step guide.

It fits 2019, 2020, and 2021 Ram 2500 and 3500 with the 6.7L Cummins, HD models included. Cab & Chassis models require modification, and trucks with airbag suspension need a routing adjustment. The hangers and clamps bolt to factory mount points with no welding, and a compatible delete tune is required to clear DPF codes. Free shipping, with standard arriving in 8–10 business days and express in 5–8. Exhaust is final sale; faulty or wrong products are replaced.
