Ram 6.7 Cummins full delete kit with Mini Maxx V2 (2010-2021)
The 2010-2021 Ram 6.7 Cummins Delete Kit with Mini Maxx V2 combines preloaded emissions-off tuning, DPF/EGR hardware, and selectable exhaust parts for Ram 2500 and 3500 pickups. The bundle stops forced regeneration after correct tuning, reduces backpressure and recirculation, and matches the 6.7L diesel engine to the selected off-road configuration.
What's included in Ram Cummins delete kit
-
Mini Maxx V2 Tuner - A preloaded 6.7 Cummins tuner with engine monitor, DTC read/clear functions, and menu-selectable power levels; no VIN-based custom file is required.
-
DPF Delete Pipe - Replaces the restrictive particulate-filter section while retaining more factory exhaust.
-
4-Inch / 5-Inch Exhaust Systems - Choose balanced 4-inch flow or maximum 5-inch flow with a deeper note.
-
EGR Valve & Cooler Delete Kit - The 6.7 Cummins EGR delete kit removes the EGR valve and cooler to stop recirculation and reduce soot and clogging.
-
Muffler / Hardware - Muffler or straight-through options are available; selected systems include application-specific pipes, stainless steel components where supplied, clamps, gaskets, and mounting hardware.

How the delete kit works on your Ram 6.7 Cummins
-
Loads the Mini Maxx V2 tune before hardware removal.
-
Removes DPF restriction and stops regeneration.
-
Disables DEF/SCR functions on 2013-2021 trucks.
-
Eliminates EGR recirculation and intake soot.
-
Matches engine calibration and exhaust flow for off-road use.
The DPF delete kit must be tuned successfully with no active codes before DPF, DEF/SCR, or EGR hardware is removed.
Installation information
The bolt-on package includes an installation guide for owners with solid mechanical skills.
2018-2021: Bypass cable required
