Everything You Need to Know About 6.7L Cummins Delete Kits (2007–2025)
What Is a Ram Cummins 6.7L Delete Kit?
A Cummins 6.7L delete kit is an engineered solution that removes the factory emissions hardware including the Diesel Particulate Filter (DPF), Exhaust Gas Recirculation (EGR) system and the Diesel Exhaust Fluid (DEF) system on 2013+ models. It replaces these components with high-flow parts and calibrated engine tuning to eliminate backpressure, regen cycles and DEF-related failures. The result is a powerful, efficient and reliable diesel engine ideal for off-road and heavy-duty use.
Early Ram Models (2007.5–2012): DPF and EGR Delete Kit
When the 6.7L Cummins debuted in 2007.5, it came with EGR and DPF systems but no DEF. Our delete kits for these models include:
- DPF Delete Race Pipe – Typically made from 409 or 304 stainless steel, replaces the factory DPF section for unrestricted flow.
- EGR Delete Kit – Includes CNC-machined block-off plates, coolant reroute hose and high-temperature hardware.
- Mini Maxx V1 Tuner (pre-programmed) – Includes DPF/EGR-off tuning with selectable power levels and gauge monitoring.
Performance Gains
- Up to +50 HP and +100 lb-ft of torque
- 3–5 MPG improvement on highway
- No more DPF regens or EGR-related drivability issues
Mid‑Generation Ram (2013–2021): Full DPF, EGR & DEF Delete
With the addition of SCR/DEF in 2013, delete kits became more comprehensive. Our complete solution includes:
- Turbo-Back or DPF/DEF Delete Exhaust – Available in aluminized or stainless steel options.
- EGR Delete Kit – Block-off plates, hose reroutes, coolant plugs, and hardware included.
- EFI Live AutoCal V3 – Tuners pre-loaded with DPF/EGR/DEF delete files and power tunes (Switch-on-the-fly available).
Quantifiable Gains
- +60 to +100 HP and +150–180 lb-ft torque
- 3–6 MPG increase under load
- Zero DEF refills or system maintenance required
Latest Rams (2022–2025): CTI Delete Tuners
Starting with 2022 models Cummins trucks came equipped with encrypted ECUs, making conventional tuning methods ineffective. Tuner Depot offers a CTI-based solution for complete emissions deletion and tuning:
- CTI Pass‑Through Programmer – Connects to a PC/laptop and interfaces with the truck’s PCM for secure tuning access.
- Remote Custom Delete Tunes (Black Bandit Series) – Applied by professional calibrators for full DPF/DEF/EGR disablement and performance optimization.
- Full Hardware Bundle – Includes SCR/DPF delete pipe, stainless exhaust section, and EGR delete kit.
Key Advantages
- No ECU removal required
- Live remote tuning with personalized calibration
- Reversible to factory settings if needed
Is a Delete Kit Right for You?
