What's a 6.7L Cummins Delete Kit?
A 6.7 Cummins Delete Kit removes factory emissions components that can restrict exhaust flow and reduce engine efficiency.
This type of delete kit is designed for Ram pickup owners looking to eliminate restrictive systems like DPF delete, EGR delete, and DEF systems, improving airflow and reducing soot buildup in the intake manifold.
What's Included in a 6.7 Cummins Delete Kit?
Each 6.7 Cummins All-in-One Kit includes a performance tuner, a DPF-delete exhaust pipe, and EGR block-off hardware to boost MPG and eliminate emission failures.
- Tuning: Pre-loaded with custom tunes to bypass sensors and prevent Limp Mode using mini maxx v2 or efi live support.
- Exhaust: A 4" or 5" stainless straight pipe to replace the restrictive DPF and SCR components in the exhaust system.
- EGR: High-flow block-off Plates and hardware included in an EGR delete kit to fully stop soot recirculation.
Key Benefits of Installing a 6.7 Cummins Delete Kit
- Reliability: Eliminate common alerts when properly tuned and DPF-related downtime.
- Fuel Efficiency: Improve airflow and fuel economy by removing exhaust restrictions.
- Engine Longevity: Stop EGR soot from entering the intake to keep engine oil cleaner.
- Performance: Unlock smoother torque delivery and sharper throttle response.
- Lower Costs: Stop buying DEF fluid with complete DEF delete and avoid expensive emission sensor repairs.
RAM 6.7L Diesel Delete Kit: Deleted vs. Stock
| Dimension |
Stock (Factory) |
Deleted (Upgraded) |
| Horsepower |
Limited by factory tuning and exhaust backpressure. |

| Fuel Economy |
Lower; active regen cycles consume extra fuel. |
Increased MPG; usually a 2–5 MPG gain without Regen. |
| Maintenance Cost |
High; requires DEF fluid and frequent emission repairs. |
Reduced; no DEF needed and emission sensors are bypassed. |
| Reliability |
Prone to DPF clogging and EGR soot buildup. |
Maximum Reliability; eliminates most common failure points. |
| Exhaust Gas Temp |
Runs hot during Regen, adding stress to the turbo. |
Lower EGTs; unrestricted flow cools the engine. |
| Legal Status |
Street Legal; EPA & CARB compliant. |
