Why Year and Model Matter Before You Buy a Delete Kit
Not all 6.7L Cummins trucks are the same under the hood, especially when it comes to emissions. Ram and Cummins gradually stacked more and more hardware onto these engines to keep pace with EPA regulations, and that means a 2008 Ram has a fundamentally different setup than a 2020 Ram.
Buying the wrong kit is a real problem in this market. A kit cut for a 2010–2012 truck will not bolt up cleanly on a 2015, and a kit built for pre-SCR applications won't address the DEF/SCR system added starting in 2013. Before you order anything, you need to know your exact model year, your cab/bed configuration, and your engine build date because Cummins made mid-year changes that affect fitment.
The best way to avoid a compatibility headache is to use EngineGo's vehicle selector, which narrows results to kits verified to fit your specific truck. Browse the full 6.7L Cummins delete kit catalog after confirming your year range.
6.7L Cummins (2007.5–2009): What to Delete
The 6.7L Cummins engine debuted mid-year 2007 in the Ram 2500/3500, replacing the 5.9L Cummins. These early 6.7s came equipped with an EGR system and a diesel oxidation catalyst (DOC), but no DPF. That makes the emissions package relatively straightforward compared to later years.
The EGR cooler and valve on these trucks are the primary failure points. They push hot, recirculated exhaust gases back through the intake to reduce NOx emissions, which gradually contaminates the intake with soot and oil vapor and can cause carbon buildup, rough idle, and elevated coolant temperatures over time.
For this generation, the core delete is the EGR cooler and valve. You'll need a proper block-off plate kit and a compatible tune to prevent the ECU from throwing codes after the EGR circuit is removed. Grab the right hardware for your build from the 2007.5–2009 Ram Cummins collection to confirm year-specific fitment.
6.7L Cummins (2010–2012): What to Delete
Starting in 2010, Ram introduced the DPF on the 6.7L Cummins lineup, a major change that added a soot trap downstream of the turbo. Now you're dealing with both EGR and DPF as a combined system. Active regeneration cycles kick in automatically to burn off accumulated soot, and when the system gets plugged or the regen cycle can't complete, you end up with hard codes, limp mode, and expensive repairs.
For 2010–2012 trucks, a complete delete means removing both the DPF and EGR hardware. The 6.7L Cummins EGR delete kit handles the valve and cooler side, while the 6.7L Cummins DPF delete pipe replaces the DPF section of the exhaust with a straight-through pipe. A 6.7L Cummins tuner is required to disable regen cycles and clear the related fault codes from the ECM.
For year-confirmed fitment options, check the 2010–2012 Ram Cummins collection.
6.7L Cummins (2013–2018): What to Delete
This is where the emissions stack gets significantly more complex. Starting in 2013, Ram added an SCR system with a DEF injector and a dedicated DEF tank. The SCR catalyst sits downstream of the DPF and uses urea-based DEF fluid to break down NOx into nitrogen and water vapor.
In practice, this means 2013–2018 trucks have three active emissions systems working in tandem: EGR, DPF, and SCR/DEF. More components, more potential failure points, and more cost when things go wrong. DEF injector failures, DEF quality sensors, and urea crystallization in cold weather are common complaints. A full delete on these trucks addresses all three systems.
You'll need a 6.7L Cummins EGR delete kit, a Cummins DPF delete pipe that accounts for the SCR section, and a tuner capable of disabling the DEF system alongside DPF regen and EGR controls. Optionally, a 6.7L Cummins CCV reroute kit is a common add-on at this stage to stop crankcase oil vapor from being recirculated back into the intake.

6.7L Cummins (2019–2024): What to Delete
The 2019 and newer Ram 2500/3500 Cummins trucks retained the same EGR + DPF + SCR/DEF architecture as the 2013–2018 generation, but Cummins and Ram updated the calibrations and tightened tolerances on the emissions hardware, which means the failure modes are similar, but the ECU is more aggressive about enforcing compliance. Code-triggered derates hit harder and faster on these trucks when emissions components start to fail.
From a delete standpoint, the process is essentially the same as the 2013–2018 generation: EGR block-off, DPF delete pipe, SCR removal, and a tuner that handles DEF disabling. However, kit fitment is not always cross-compatible between the two generations, so confirm your exact model year before ordering. Hardware changes in 2019 include an updated EGR cooler design and revised DEF tank plumbing that requires matching delete hardware.
All confirmed-fit options for late-model trucks are available in the 2019–2024 Ram Cummins collection. If you want to do a full one-and-done order, the Cummins full delete kit bundles the tuner, delete pipe, and EGR hardware into a single package for the correct year range.
Compatibility Checklist Before You Buy
Getting the wrong kit is a waste of time and money. Run through this checklist before you add anything to your cart:
- 1. Confirm your model year. If your build date is between January and July 2007, verify whether your truck is a "2007" or "2007.5". This matters because the 6.7L engine swap happened mid-production year.
- 2. Confirm your cab and bed. Some exhaust delete pipes are fitment-specific based on cab configuration (regular, crew, mega cab) due to frame and exhaust routing differences.
- 3. Know your current emissions hardware. If you're not sure whether your truck has DEF, look for a blue DEF filler cap near the fuel door. If it has one, you have an SCR system (2013+) and need a DEF-capable tuner.
- 4. Check kit compatibility on EngineGo. Use the vehicle selector to input your year, make, model, and engine, and the system will filter the catalog to only show parts confirmed to fit your truck. This is the fastest way to avoid ordering a kit that won't work.
FAQs
Do I need a tuner to delete a 6.7L Cummins?
Yes, every time. The ECU monitors all emissions components and will put your truck in limp mode without a tune that tells it the hardware has been removed. A tuner isn't optional — it's part of the delete.
What's the difference between a DPF delete pipe and a full turbo-back exhaust?
A DPF delete pipe replaces the DPF section only and keeps the factory up-pipe intact. A turbo-back system replaces everything from the turbo outlet back, including the DPF and exhaust piping, and is a bigger job but delivers the most flow improvement.
Will deleting my 6.7L Cummins affect my warranty?
Yes. On trucks still under factory warranty: yes, emission-related warranty coverage would be voided for components affected by the modification.
Can I delete just the EGR and leave the DPF?
Technically possible, but generally not recommended on 2010+ trucks. The two systems are interdependent, and a properly tuned delete handles both together for the cleanest result.
