Best 6.7 Cummins Delete Kits (2026): Ranked & Compared

🔑 Key Takeaways

  • The best 6.7 Cummins delete kits include a grid heater delete or relocation plate — the factory grid heater bolt is a known failure point that can fall into the intake and destroy the engine.
  • EZ Lynk tuning is the gold standard for deleted 6.7 Cummins (2013+), offering custom tuning, transmission tuning for 68RFE, and real-time monitoring via smartphone — SCT and MM3 are solid budget alternatives.
  • 4-inch vs 5-inch exhaust: 4" is sufficient for stock-to-mild tunes (up to 550 HP), while 5" is recommended for aggressive tuning (550+ HP) to keep EGTs manageable under heavy towing.
  • Weight-loss kits for 2019+ Ram Cummins are more complex due to encrypted ECUs — you'll need an ECM exchange or bench-unlock service before tuning, adding $500-$1,000 to the total cost.
  • Budget $1,800-$3,000 for a complete 6.7 Cummins delete package; the delete itself can be done in a weekend (8-12 hours DIY), but professional installation is recommended for the EGR cooler R&R.

Understanding key considerations is crucial for making informed decisions when searching for the best delete kit for the 6.7 Cummins engine. The removal kit allows you to remove specific components from the engine that may restrict airflow and hinder performance, making the engine more robust and efficient. This article will share how to choose the best deletion kit and provide practical suggestions for optimizing performance, helping you explore options for deleting the 6.7 Cummins engine.

Precautions for selecting the best deletion toolkit:

The removal kit is a popular modification for diesel truck enthusiasts, especially those who use the 6.7 Cummins engine. By removing EGR (Exhaust Gas Recirculation), DPF (Diesel Particulate Filter), and DEF (Diesel Exhaust Fluid) systems, the removal kit improves engine performance by increasing horsepower and torque, while eliminating issues such as exhaust back pressure and blockage risk.
Quality and reliability: Choose a manufacturer of deletion kits known for providing high-quality and reliable products with positive reviews.
Compatibility: Ensure that the selected deletion kit is compatible with your specific vehicle model and its engine to ensure a smooth installation process.
Regulatory compliance: Familiarize yourself with local emission regulations to ensure that the selected removal kit complies with relevant standards and regulations.

What does the deletion toolkit include?

The complete removal kit of Cummins typically consists of several components:
EGR removal kit: Replace or bypass the exhaust gas recirculation system.
DPF removal kit: Remove or disable diesel particulate filters.
DEF removal kit: Disable selective catalytic reduction system, which uses DEF to treat exhaust gases.
Adjusting software: usually included to ensure optimal vehicle operation after disassembling components.

Suggestions for optimizing the performance of the 6.7 Cummins engine:

Regularly maintain the engine by replacing the air filter, fuel filter, and oil to keep it in good working condition.
Consider upgrading the engine control unit (ECU) to optimize parameter settings and ensure compatibility with the removed kit.
Explore other performance enhancing components such as turbocharged systems or exhaust system modifications based on your vehicle usage and needs.

DPF/EGR/CCV Delete All-in-One Kit from Seguler Auto Parts:

Use the Seguler EGR/DPF/CCV deletion kit to improve the performance of the 6.7-liter Cummins. This multifunctional kit is designed specifically for the 2013-2017 Dodge Ram 2500/3500 6.7L Cummins diesel truck, including EGR removal kit, DPF removal kit, CCV re routing kit, and Mini Maxx V2 removal tuner.

A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs.This eliminates the oil buildup on the turbo compressor and maintains intercooler cleanliness. 90° vent hose encourages oil drain back and helps eliminate drips.
The CCV system dumps the crankcase gasses into your turbo inlet post air filter which causes an oily buildup on the turbo compressor wheel. If crankcase blow-by is higher than normal these gasses can also coat the inside of the intercooler which lowers its efficiency.

With the Mini Maxx V2 Delete Tuner, you can safely remove emission components without triggering check engine lights or diagnostic codes. This kit is a complete solution that maximizes engine power, fuel economy, and lifespan while reducing maintenance costs.

Legal Considerations When Using

One of the key factors to consider when installing the removal kit for your 6.7 Cummins is the legal aspect. Many states, especially California, have strict emission regulations, which makes the use of removal toolkits a problem. Dismantling components such as DPF or EGR may violate these emission regulations and may result in fines or failure to pass state inspections. It is important to verify the specific emission laws in your state before installing the removal toolkit. In some areas, deleting toolkits is illegal on the streets and can only be used for off-road purposes.
Another factor to consider regarding vehicle inspection is that after installing the removal kit, your truck may not pass the emissions inspection. Some states require vehicles to pass emission tests before registration, and if your truck is not equipped with the necessary emission control devices, it may not pass the inspection. It is important to understand the local laws to avoid any complex situations with vehicle registration.

Conclusion:

Choosing the best removal kit for your 6.7 Cummins requires careful consideration of several key factors, including performance improvements, compatibility with trucks, and the legal impact of modifying emission systems. A carefully selected deletion kit can significantly improve the power and overall efficiency of the engine, and before making any modifications, it is necessary to fully understand the legal environment in your region. To ensure that your modifications comply with regulations.
By following this guide, you will acquire the knowledge to make decisions that meet your performance goals and legal requirements, ensuring that your 6.7 Cummins engine achieves optimal performance.
