6.7 Cummins Delete Kit — 2007.5–2024 Ram DPF, EGR & DEF Delete

Quick Answers: 6.7 Cummins Delete Kit — 2007.5–2024 Ram DPF, EGR & DEF Delete

• What does a 6.7 Cummins delete kit include?

  A 6.7 Cummins delete kit covers the three main emissions systems — EGR, DPF, and DEF. You get an EGR delete kit to block off the cooler and valve, a DPF delete pipe to replace the factory particulate filter, and a tune to recalibrate your ECU. The Diesel Dudes bundles are spec-matched for your exact model year so every component fits and the tune is calibrated to the hardware.

• Is deleting a 6.7 Cummins worth it?

  For off-road and competition use, yes. A deleted 6.7 Cummins runs cleaner, runs cooler, and makes more power without the EGR soot fouling your intake or the DPF choking your exhaust. Regen cycles stop. Oil contamination from the EGR system stops. Owners consistently report 50-100 hp gains and significantly improved reliability on high-mileage trucks.

• What year 6.7 Cummins can be deleted?

  Any 2007.5 through 2024 Ram 2500 or 3500 with the 6.7L Cummins can be deleted. The third-gen platform ran 2007.5-2012, fourth-gen ran 2013-2018, and fifth-gen covers 2019-2024. Each generation has slightly different emissions hardware, so make sure your delete kit is year-specific. The Diesel Dudes carries kits for all three generations.

• How much horsepower does a Cummins delete add?

  A properly tuned 6.7 Cummins delete typically adds 60-120 horsepower and 150-200 lb-ft of torque depending on tune aggressiveness and the truck condition. The tune does the heavy lifting — the delete hardware removes the restrictions. Most owners see the biggest gains at mid-range RPM where the DPF and EGR were creating the most backpressure.

• Do you need a tuner with a delete kit?

  Yes, always. Removing the EGR and DPF hardware without a supporting tune leaves your ECU in an error state — you will get check engine lights and the truck may enter limp mode. The tune rewrites the emissions logic, adjusts fueling, and optimizes boost for the new exhaust flow. Do not install delete hardware without the matching tune.

• How long does a 6.7 Cummins delete take to install?

  Plan for 4-8 hours depending on your year and setup. The EGR delete typically takes 2-4 hours — removing the cooler and installing block-off plates requires working around the intake and coolant lines. The DPF delete pipe swap adds another 1-2 hours. A shop with a lift can do it in an afternoon. Home installs on a jackstand setup may take a full day.
