6.7 Cummins Delete Kit

Why Does Your 6.7 Cummins Need a Delete Kit?

Soot and Carbon Pack the EGR Cooler

The stock EGR on the 6.7 Cummins routes dirty exhaust back into the intake. Carbon cakes the cooler and throttle valve until airflow drops and the truck runs lazy. An EGR delete kit seals that passage with billet plates so only clean air reaches the cylinders.

DPF Regens Kill Fuel Economy and Towing Range

The diesel particulate filter clogs and forces nonstop regen cycles that burn extra fuel and drop range. Our T304 stainless DPF delete for 6.7 Cummins replaces the filter with a free flowing 4 inch run, ending regens for good and freeing up low end torque.

Throttle Valve and CCV Failures Trigger Codes

The intake throttle valve sticks and the crankcase filter loads up, both throwing check engine lights. A throttle valve delete and CCV reroute remove those failure points so the 6.7L pulls strong on every pass.

What Can a Delete Kit for 6.7 Cummins Solve?

Seal the EGR Cooler and Throttle Valve

CNC-machined 6061 T6 billet plates cap the EGR cooler and throttle valve ports, cutting soot and dropping exhaust gas temps across the board.

Open the Exhaust With a DPF and DEF Pipe

A T304 stainless DPF, EGR, and DEF delete pipe swaps the clogged emissions stack for a mandrel-bent 4-inch exhaust. Backpressure falls, turbo spool quickens, and DEF refills become a thing of the past.

Reroute the CCV Away From the Intake

The CCV reroute kit for 6.7 Cummins moves crankcase vapor out of the intake tract with a billet breather and hose. Oil film stops building up on the manifold, keeping the engine cleaner between services.

Frequently Asked Questions about 6.7 Cummins Delete Kits

What is included in a 6.7 Cummins delete kit?

A 6.7 Cummins delete kit strips the restrictive emissions hardware from the Ram 2500 or 3500 inline six. A basic EGR delete covers the cooler and throttle valve with billet block off plates and Viton sealed gaskets.
A full delete adds a DPF, EGR, and DEF pipe plus a CCV reroute so the engine runs without regen. Every kit is built around the 2007.5 to 2019 6.7L and ships with the hardware needed for a clean install.

Which Ram years fit the 6.7 Cummins EGR and DPF delete kits?

The early EGR cooler deletes cover 2007.5 to 2009 trucks before DEF was added. The 2010 to 2014 kits target the engine after urea and SCR arrived, while the 2013 to 2019 kits fit the late revisions.
Cab and chassis trucks run a dedicated 2013 to 2018 EGR delete, and the CCV reroute spans 2007.5 to 2017. Always match the kit to your build date, because the 6.7L changed EGR and exhaust hardware across those years.

Do you need a tuner with a 6.7 Cummins delete kit?

Yes, a deleted 6.7 Cummins must be tuned to run right. The ECU watches the EGR, DPF, and DEF signals, and without a delete tune it throws codes and drops into limp mode.

A 6.7 Cummins MiniMaxx diesel tuner or EFI Live calibration clears those emissions parameters and dials in fueling. Pair the hardware delete with a proper tune so the truck pulls strong instead of just throwing warning lights.

What is the difference between an EGR delete and a DPF delete on the 6.7?

An EGR delete blocks exhaust gas recirculation, cutting soot and lowering intake temps. A DPF delete removes the diesel particulate filter with a 4-inch stainless pipe for free-flowing exhaust.
EGR work is under the hood at the cooler and throttle valve. DPF work is underneath at the exhaust. Most owners do the EGR first for quick temp gains, then add the DPF and DEF pipe for full flow.

Does deleting the 6.7 Cummins improve horsepower, torque, and fuel economy?

Most owners report a clear bump in low-end torque and smoother throttle response after deleting. With the DPF and DEF gone and a tune loaded, the 6.7L stops wasting fuel on regen cycles.

Real-world gains show stronger tow power and better highway mileage. The exact numbers depend on your tune and how the truck is driven, but the drop in backpressure is the key win for these Rams.

How long does a 6.7 Cummins EGR and DPF delete install take?

A basic EGR cooler or throttle valve delete runs about two to three hours with hand tools and a floor jack. The 4-inch DPF DEF pipe adds another hour underneath the truck.

Most DIY owners finish a full setup in a weekend. Step-by-step guides and our 24/7 support keep the job on track if you hit a snag during the install.

What does a CCV reroute or crankcase filter delete do on a 6.7 Cummins?

The stock crankcase filter vents oily vapor straight back into the intake, coating the manifold and boots in sludge. A CCV reroute kit moves that vapor out with a billet breather and hose.
That keeps the intake tract dry and cuts the carbon load the EGR already adds. It is a small job that pays off with cleaner intakes and longer service intervals on the 6.7L.

Will a deleted 6.7 Cummins pass emissions or run without codes?

Off the emissions bench, a properly deleted and tuned 6.7 Cummins runs clean with no check engine light, because the tune disables the EGR, DPF, and DEF monitors. The truck is built for competition and closed-course use.

On a public road emissions test, a deleted truck will not pass, since the systems are physically gone. Plan the build for the right application and pair it with a quality tuner to avoid ghost codes.

Are 6.7 Cummins delete kits legal for street use?

These 6.7 Cummins delete kits are intended for competition and closed-course off-road use only. Federal law prohibits tampering with emissions controls on vehicles driven on public roads, and removing the EGR, DPF, and DEF can carry fines.

Verify your local rules and confirm your truck year before ordering, because the kits are year-specific and a wrong fit wastes time. Every order still ships with free shipping, a 1-year warranty, and our 45-day return policy so you can buy with confidence for the right application.

What materials are 6.7 Cummins delete kits built from?

The EGR block-off plates are CNC-machined 6061 T6 billet aluminum for a precise, warp-free seal. Exhaust pipes and mufflers use T304 stainless steel with precision TIG welds that hold up under heat.

Every junction gets high-temperature Viton O-rings and reinforced silicone couplers to stop leaks. The parts are tested under extreme conditions, so your deleted 6.7L stays reliable whether you are towing or running the strip.
