Quick Answer:
The best delete kit for a 6.7 Cummins depends on 4 things: your Ram model year, whether the truck is a pickup or Cab & Chassis, which emissions components are being changed, and whether the kit includes compatible tuning support. Many shoppers compare all-in-one DPF/DEF/EGR kits, EGR-only kits, DPF race pipes, CCV/PCV reroute kits, and tuner bundles from brands such as SPETUNER, RaceME, EFI Live, Mini Maxx, and other diesel performance suppliers. Before buying, confirm fitment and legality. Removing, bypassing, defeating, or disabling required emissions equipment on public-road vehicles may violate federal, state, and local law.
If you are shopping for a 6.7 Cummins delete kit, the hardest part is not finding parts. The hard part is choosing a kit that matches your truck's year, emissions layout, tuner requirement, and intended use. A kit for a 2013-2018 Ram 2500 pickup may not fit a 2011-2018 Cab & Chassis truck, and a 2019+ truck can have different tuning and ECM compatibility requirements.
This guide explains how to compare 6.7 Cummins delete kit types, what is usually included in a complete bundle, how to choose by model year, what tuner support means, and what to check before ordering from SPETUNER or any other supplier.
Important Legal and Compliance Note
Delete kits are emissions-related parts. In the United States, the EPA warns that installing defeat devices or tampering with emissions controls can lead to enforcement and penalties. California also has a CARB Executive Order process for certain legal aftermarket parts, and other states may have their own inspection or anti-tampering rules.
Do not remove, bypass, defeat, or disable required emissions controls on vehicles used on public roads unless the modification is clearly allowed by applicable law. If a product is sold for racing, competition, export, or off-road use, verify what that means for your vehicle, your state, and your actual use case before purchase.
What Is a 6.7 Cummins Delete Kit?
A 6.7 Cummins delete kit is a parts package that changes or removes one or more factory emissions systems on a Ram diesel truck. Depending on the kit, it may involve the DPF, EGR, DEF/SCR system, exhaust piping, CCV/PCV routing, sensors, and engine tuning support.
Owners usually search for these kits because of regen problems, clogged DPF concerns, EGR cooler failures, DEF system faults, high repair costs, towing performance complaints, or off-road/competition build plans. Those symptoms can also come from unrelated engine, turbo, fuel, sensor, or exhaust problems, so diagnose the truck before ordering parts.
What Does a Complete 6.7 Cummins Delete Kit Include?
| Component | What It Does | Buying Note |
|---|---|---|
| DPF delete pipe or exhaust section | Replaces the factory diesel particulate filter section in non-compliant/race-use setups. | Check pickup vs Cab & Chassis, wheelbase, sensor locations, and 4-inch vs 5-inch pipe options. |
| EGR delete hardware | Changes the exhaust gas recirculation path using plates, fittings, hoses, or coolant reroute parts. | Confirm model year, engine bay layout, coolant routing, and whether the EGR cooler is affected. |
| DEF/SCR-related parts | Addresses DEF/SCR-related components where included in a full delete bundle. | 2013+ trucks commonly require extra attention because SCR/DEF systems became part of the package. |
| Tuner or tuning support | Helps the ECM work with the changed hardware and avoids drivability errors where legally used. | Compatibility varies by model year, ECM, tuner platform, and calibration provider. |
| CCV/PCV reroute parts | Helps manage crankcase ventilation and oil vapor routing on some builds. | This is not the same as a DPF/EGR/DEF delete, but it is often shopped alongside diesel reliability parts. |
| Hardware and instructions | Includes clamps, block-off plates, gaskets, fittings, hoses, and install guidance where provided. | Review the product page carefully so you know what is included and what must be purchased separately. |
Best Delete Kit Type by Buyer Goal
| Kit Type | Best For | Important Reminder |
|---|---|---|
| All-in-one DPF/DEF/EGR delete kit with tuner | Competition/off-road builds where the owner wants one matched parts bundle. | Usually, the most complete option, but it has the highest legal, tuning, and fitment responsibility. |
| DPF/DEF delete pipe or race pipe | Replacing the exhaust aftertreatment section in race-use applications. | A pipe-only purchase can still require tuning support and can leave other system faults if mismatched. |
| EGR delete kit only | Owners focused on EGR cooler, EGR valve, or intake soot concerns. | Do not assume standalone EGR hardware works without tuning or other compatibility checks. |
| CCV/PCV reroute kit | Reducing oil vapor contamination in the intake path on compatible trucks. | This is a supporting reliability-style part, not a full emissions delete kit. |
| High-flow exhaust system | Owners who want sound, flow, or exhaust replacement options without choosing a full all-in-one bundle. | Confirm whether the system is emissions-compliant for your truck and location. |
Choose by 6.7 Cummins Model Year
Fitment is the number 1 buying filter. Ram Cummins emissions layouts changed across generations, and Cab & Chassis trucks are often different from pickup trucks. Always confirm your year, model, engine, wheelbase, bed/cab configuration, emissions label, and product-page notes before ordering.
| Truck Range | Common Search Term | Buying Focus |
|---|---|---|
| 2007.5-2009 Ram 2500/3500 6.7 Cummins | 2007.5-2009 6.7 Cummins delete kit | Early 6.7L fitment, DPF/EGR layout, pickup vs Cab & Chassis differences. |
| 2010-2012 Ram 2500/3500 6.7 Cummins | 2010-2012 6.7 Cummins delete kit | Year-specific exhaust routing, EGR hardware, and tuner compatibility. |
| 2011-2018 Ram Cab & Chassis 6.7 Cummins | 6.7 Cummins Cab & Chassis delete kit | Frame, exhaust, wheelbase, and commercial-truck fitment can differ from pickup kits. |
| 2013-2018 Ram 2500/3500 6.7 Cummins | 2013-2018 6.7 Cummins delete kit | DPF, EGR, and SCR/DEF-related system compatibility plus tuner support. |
| 2019-2021 Ram 2500/3500 6.7 Cummins | 2019-2021 6.7 Cummins delete kit | Updated truck generation, exhaust layout, ECM/tuner compatibility, and sensor provisions. |
| 2022+ Ram 6.7 Cummins | 2022+ or 2025 6.7 Cummins delete kit | High compliance and tuning risk. Confirm current laws, ECM support, warranty impact, and whether any product is appropriate for your use case. |
Do You Need a Tuner for a 6.7 Cummins Delete Kit?
In many delete-kit discussions, the tuner is just as important as the hardware. Removing or changing emissions-related parts can trigger diagnostic codes, limp mode, regen problems, sensor faults, and drivability issues if the ECM is not compatible with the hardware configuration. Commonly researched tuner names include Mini Maxx, EFI Live, RaceME, EZ Lynk, and other diesel calibration platforms.
Do not buy a tuner by name alone. Confirm 5 things before ordering: model year, ECM support, transmission tuning needs, included files or unlock process, and whether the tuner is legal for your intended vehicle use. Newer trucks may have additional locked-ECU or security-gateway requirements.

Buying Checklist Before Ordering
- Confirm the truck's exact year, model, engine, and pickup vs Cab & Chassis configuration.
- Check whether your truck is 2007.5-2009, 2010-2012, 2013-2018, 2019-2021, or 2022+.
- Identify whether you need DPF, DEF/SCR, EGR, CCV/PCV, exhaust, tuner, or sensor-related parts.
- Review product photos and compare sensor ports, flange style, pipe diameter, exhaust length, and brackets.
- Confirm whether the kit includes a tuner, tuning files, hardware, gaskets, hoses, clamps, and instructions.
- Check compatibility with your transmission, current tune, intake, turbo, exhaust, and emissions layout.
- Confirm warranty impact, inspection requirements, and local emissions rules before purchase.
- Use SPETUNER's installation guide or product support if you need help matching parts to the truck.
Common Buying Mistakes
- Buying a pickup kit for a Cab & Chassis truck.
- Ordering by engine size only and ignoring model year or emissions layout.
- Choosing a pipe-only kit when the truck also needs tuner compatibility checks.
- Assuming every tuner supports every 6.7 Cummins ECM.
- Expecting guaranteed horsepower, torque, or MPG gains from hardware alone.
- Ignoring check-engine lights, limp mode, sensor faults, or regen history before diagnosis.
- Overlooking federal, state, local, CARB, inspection, or warranty consequences.
Performance Expectations
Many diesel owners shop delete kits because they want stronger throttle response, lower exhaust restriction, fewer regen-related issues, or better towing feel. Results vary widely. Final performance depends on truck condition, tune quality, turbo health, fuel system health, transmission setup, exhaust size, driving load, and supporting parts.
Be careful with guaranteed power or fuel-economy claims. A well-matched race/off-road setup may feel stronger than a failing stock emissions system, but a delete kit is not a magic fix for bad injectors, weak turbo performance, boost leaks, failing sensors, or poor maintenance.
