6.7 Cummins DPF Delete Kit

Why Does Your 6.7 Cummins Need a DPF Delete?

Clogged DPF and Endless Regen Cycles

The factory Diesel Particulate Filter loads with soot until the truck forces a regen, burning fuel to clear itself. On a 6.7 Cummins, that means lost miles per gallon, heat soak, and a filter that eventually clogs for good. A DPF delete ends the cycle and keeps the exhaust flowing.

Rising Exhaust Gas Temperatures Under Load

Restricted exhaust raises exhaust gas temperatures every time you pull a grade or haul a load. High EGTs cook the turbo and shorten engine life. Removing the DPF with a mandrel-bent 409 stainless pipe drops those temps and protects the turbo on the jobs that matter.

Limp Mode From Sensor and Pressure Faults

The 6.7L Cummins watches pressure and temperature sensors tied to the emissions system. When a filter is removed without proper tuning, the ECM logs faults and drops the truck into limp mode. A delete paired with a tuner keeps the truck running clean and strong.

What Can a DPF Delete Solve?

Lower Backpressure With Mandrel-Bent 409 Stainless Pipe

A high-flow 409 stainless delete pipe replaces the restrictive factory section, opening the exhaust and letting the turbo spool faster. Precision TIG welds and high-temperature hardware keep the system sealed under heat.

Tuner Integration to Calibrate the ECM

Every 6.7 Cummins delete needs a tuner to tell the ECM the emissions hardware is gone. Our bundles pair Mini Maxx tuners with the pipe so deleted sensors stop throwing codes.

FAQs about 6.7 Cummins DPF Delete Kit

What does a 6.7 Cummins DPF delete do?

A 6.7 Cummins DPF delete replaces the factory Diesel Particulate Filter with a high-flow 409 stainless pipe. That removes the exhaust restriction that forces constant regeneration and robs torque on every pull. With the filter gone, exhaust gas temperatures drop and the turbo spools quicker, which is exactly what a working truck needs.

Will a DPF delete on a 6.7 Cummins require a tuner?

Yes. Every 6.7 Cummins DPF delete requires a diesel tuner to recalibrate the ECM. Without a tune the truck throws diagnostic trouble codes and drops into limp mode the moment the sensors read a missing filter. Our all-in-one bundles pair the pipe with a Mini Maxx tuner so the install is complete out of the box.

What is the best DPF delete kit for a 6.7 Cummins?

The best 6.7 Cummins DPF delete depends on your year and how complete you want the build. For 2007.5-2012 trucks the 5 inch turbo back system is the proven choice, while 2013-2018 rigs run the 5 inch turbo back delete pipe. Owners who want a single box pick the 4 inch DPF EGR DEF delete all-in-one with a Mini Maxx tuner.

Can I run a 6.7 Cummins DPF delete without a programmer?

You can bolt the pipe on without a tuner, but the truck will not run right. The ECM still expects the DPF and will log faults that trigger limp mode within a few miles. Running a 6.7 Cummins delete without a programmer is only safe on a chassis dyno or competition and closed-course off-road use only.

How much does it cost to delete the DPF on a 6.7 Cummins?

Costs vary by kit, but a standalone 409 stainless DPF delete pipe starts around the low triple digits while all-in-one bundles with a tuner run higher. Pricing shifts with pipe diameter, the inclusion of EGR or CCV deletes, and whether you add a muffler. We ship free and back every order with a 1-year warranty and 45-day returns, so the total landed cost stays predictable.

Will a 6.7 Cummins DPF delete improve fuel mileage?

Removing the DPF cuts exhaust backpressure, which helps fuel economy on long hauls and heavy towing. Many owners report better mileage once the truck stops burning fuel for active regen cycles. Real world gains depend on driving style, tune, and whether the EGR is deleted at the same time.

Is a 6.7 Cummins DPF delete legal?

These 6.7 Cummins DPF, EGR, and DEF delete components are intended for competition and closed-course off-road use only. Removing emissions control hardware on a registered on-road vehicle violates EPA regulations and may not be legal in your area. Confirm local laws before purchase, and never operate a deleted truck on public roads unless exempt under your jurisdiction.

Which years are supported by 6.7 Cummins DPF delete kits?

This collection covers 2007.5 through 2024 Ram 2500, 3500, 4500, and 5500 trucks with the 6.7L Cummins.
Generation breaks are 2007.5-2012, 2013-2018, and 2019-2024, each with its own pipe routing and sensor setup.
Some kits exclude Cab and Chassis or air-suspension models, so match the fitment notes before ordering.

What size exhaust pipe should I choose, 4 inch or 5 inch?

Both 4 inch and 5 inch 409 stainless pipes fit the 6.7 Cummins, and the right size depends on power level.
Stock-power and daily tow rigs do fine with 4 inch, while built engines pushing heavy fuel benefit from the 5 inch turbo back layout. Either way the mandrel-bent design keeps flow smooth and the install clean.

Do you offer free shipping and warranty on 6.7 Cummins delete kits?

Yes. Every 6.7 Cummins DPF delete kit ships free with fast delivery to get you back on the road sooner. We also include a 1-year warranty tested under extreme conditions and a 45-day return policy for risk-free shopping.
