Ram Cummins 6.7L All-in-One DPF/EGR Delete Kit (2007.5-2009)

Overview

This 6.7 Cummins delete kit is built for 2007.5–2009 Ram 2500HD and 3500HD trucks equipped with the 6.7L Cummins. Designed for off-road and competition use, it removes the factory DPF and EGR systems while pairing vehicle-specific hard parts with matched tuning to eliminate common emissions-related failure points. The result is improved drivability, reduced exhaust restriction, and more consistent engine performance under load.

Compatibility

Technical Specifications

Delete Kit Includes

• H&S Mini Maxx Tuner – Recalibrates the ECM to properly disable DPF and EGR functions, preventing check engine lights, derate conditions, and regeneration events after emissions removal.
• 4 inch Stainless Steel DPF Delete Pipe – Mandrel-bent 304 stainless construction reduces exhaust backpressure compared to the factory DPF assembly and improves overall exhaust flow.
• Complete EGR Delete Kit – Eliminates the EGR valve and cooler to prevent soot buildup in the intake and reduce under-hood heat.

Performance Benefits

• Improved Throttle Response – Reduced exhaust restriction and corrected fueling logic provide quicker pedal response and smoother power delivery.
• Lower Engine Temperatures – Removing EGR flow helps reduce intake air and coolant temperatures, especially during towing or sustained load.
• Fuel Economy Improvement – Eliminates fuel-heavy DPF regeneration cycles that negatively impact MPG.
• Increased Reliability – Fewer emissions components mean fewer common failure points over the long term.

Installation Notes

Professional installation is recommended. The truck must be tuned with the included Mini Maxx and verified free of diagnostic trouble codes before removing any emissions components. Standard hand tools are required, along with exhaust removal experience and access to the EGR cooler area.

Frequently Asked Questions

Q: Is this a complete delete kit for a 2008 6.7 Cummins?
A: Yes. This kit includes the Mini Maxx tuner, 4 inch DPF delete pipe, and full EGR valve and cooler delete components for 2007.5–2009 Ram 2500HD and 3500HD trucks.

Q: Can the truck be driven without installing the tuner first?
A: No. The ECM must be properly tuned before any DPF or EGR components are removed to avoid fault codes, limp mode or ECM damage.

Q: What performance changes should I realistically expect?
A: Trucks typically see improved throttle response, smoother power delivery, and noticeable fuel economy gains once regeneration cycles are eliminated. Results vary by tune level and driving conditions.

Q: Are all required parts included?
A: All major components needed for a full DPF and EGR delete are included. Optional upgrades such as cold air intakes, grid heater deletes or gauges are sold separately.

Q: Is this kit legal for street use?
A: No. This product is intended for off-road and competition use only and is not legal for use on public roads.
