Ram 6.7 Cummins full delete kit with Mini Maxx V1/V2 (2007.5-2009)
The 2007.5, 2008, 2009 Ram 6.7 Cummins Delete Kit with H&S Mini Maxx V1/V2 combines engine tuning, DPF/catalyst removal, EGR removal, and selectable exhaust hardware in one off-road package. The complete setup eliminates forced regeneration, reduces exhaust restriction and soot recirculation, and provides selectable horsepower levels for daily driving, towing, or performance use.
What's included in 6.7L Cummins delete kit
-
H&S Mini Maxx V1 or Mini Maxx V2 Tuner -Β The 6.7 Cummins tuner recalibrates the ECM for the modified DPF and EGR configuration, provides selectable power levels, supports SOTF operation, and can monitor engine parameters.
-
EGR Valve & Cooler Delete Kit -Β The 6.7 Cummins EGR delete kit removes the EGR valve and cooler, reducing exhaust recirculation, soot buildup, intake clogging, and heat transferred through the EGR system. The package includes the required block-off plate and mounting hardware.
-
DPF/CAT Delete Pipe -Β The 4-inch stainless steel delete pipe, or race pipe, replaces the factory particulate filter and catalyst section while retaining more of the original exhaust system.
-
4-Inch Exhaust System - Built from T-409 stainless steel, the 4-inch option provides increased flow, corrosion resistance, and a moderate exhaust tone for daily use and towing.
-
5-Inch Exhaust System -Β The 5-inch option provides the largest exhaust path and a deeper sound. T-409 stainless steel construction and supplied clamps/mounting hardware for the 5-inch system.
-
Muffler Option -Β Choose Straight Pipe for maximum sound or With Muffler for reduced volume and drone.

How the delete kit works on your 6.7 Cummins
-
Loads the Mini Maxx tune for the modified emissions configuration.
-
Removes DPF and catalyst restriction to stop regeneration cycles.
-
Eliminates EGR recirculation to reduce soot and intake contamination.
-
Provides selectable SOTF power levels for different driving demands.
-
Reduces backpressure and EGTs for improved engine response.
The DPF delete kit requires the correct tuner calibration before the truck is operated with the factory DPF and EGR hardware removed.
Installation information
The kit includes installation instructions, and an owner with basic-to-intermediate mechanical skills can install the bolt-on hardware without fabrication. The tuner should be programmed before the factory emissions hardware is removed.
Corrosion, seized exhaust clamps, and limited access around the EGR cooler can increase install time.

Early 6.7L Cummins service information specifically documents EGR-related faults such as P0402, P040B, and P0405, while DPF faults commonly include P242F, P2459, and P2463.
Correct calibration also prevents emissions-related limp mode conditions caused specifically by missing DPF or EGR hardware.
The 2007.5-2009 6.7L Cummins does not use a factory urea DEF system, so DEF/SCR codes are not part of the delete calibration. Send us your VIN and transmission information if you need the exact tuner and exhaust configuration confirmed before ordering.
