2019–2022 Ram 6.7L Cummins DPF & CAT Delete Pipe Configurations
This exhaust hardware replaces sections of the factory diesel aftertreatment exhaust on listed Ram 2500 and Ram 3500 pickups. Four-inch and five-inch configurations are available for 6.7L Cummins diesel applications, with model-year coverage determined by the selected SKU.
This is a DPF/CAT race-pipe configuration, not an EGR delete kit, CCV reroute kit, or electronic tuner. Compatible tuning is required, and the selected pipe configuration, factory exhaust layout, cab style, and emissions configuration must match the vehicle before installation.

What This DPF Delete Pipe Changes
The pipe configuration replaces emissions-related sections of the factory exhaust rather than blocking an EGR passage or rerouting crankcase ventilation. Removing DPF, catalytic, DOC, SCR, or related sensor-equipped exhaust sections changes the factory diesel aftertreatment and regeneration system.
Components differ between the race-pipe and downpipe-back configurations. Select the required SKU before ordering and check the selected configuration before installation.
What Is Included
- The selected race-pipe, muffler-equipped, or downpipe-back exhaust configuration
- Clamps
- Hangers
- Installation hardware
Some factory hardware is reused. Package contents vary by selected configuration.
Tune and Additional Requirements
A compatible DPF-delete tuner or calibration is required when emissions-related exhaust components and sensors are removed. The tuner is sold separately. View the Flashark Mini Maxx V2 Delete Tuner.
Operating the vehicle without a compatible calibration can result in check-engine lights, diagnostic trouble codes, interrupted regeneration logic, reduced-power operation, or limp mode. Tuning results depend on the vehicle calibration, installed hardware, sensor configuration, and installation quality; the absence of warning lights cannot be guaranteed.
Installation Notes
- Professional installation is recommended.
- An automotive lift can improve access to the factory exhaust system.
- Cutting may be required on shorter wheelbase or bed/cab configurations.
- Clamps, hangers, and supplied hardware must be tightened and checked for exhaust leaks.
- Some original hardware must be retained and reused.
- Check pipe routing, clearances, joints, hangers, and sensor-related connections before operating the vehicle.
