EGR/DPF Delete Kit for 2019-2025 Dodge Ram 2500/3500 6.7L Cummins
---tab Description---
SPEtuner DPF Delete Exhaust System & Complete EGR Delete Kit For 2019-2025 RAM 2500 3500 6.7L Cummins
SPEtuner 6.7L Cummins Delete Suite delivers maximum power, fuel savings, and durability. Includes high-flow DPF delete race pipe + heavy-duty EGR delete kit. Removes restrictive filters and soot-clogged EGR parts to slash backpressure, lower EGTs, sharpen turbo response, and eliminate forced regen cycles. Plug-and-play, engineered for severe off-road and race use.
Key Features
- Max Exhaust Scavenging: Mandrel-bent piping eliminates factory restrictions, slashes backpressure, and sharpens turbo response for instant power.
- Total EGR Elimination: Removes the failure-prone EGR cooler and valve, blocking soot-laden exhaust from contaminating your intake manifold.
- Lower EGTs: Boosts thermal efficiency to keep temps safely low during heavy towing, hauling, or high-load pulls.
- Heavy-Duty Durability: Built from premium corrosion-resistant materials to withstand extreme heat, high boost, and harsh conditions.
- Pure Engine Longevity: Keeps soot and hot gases out of your intake, protecting valves, pistons, and injectors for hundreds of thousands of miles.
Specifications
- Material: T-409 Stainless Steel(Magnetic)
-
Thickness: 2mm thick for long-lasting durability and heat resistance.
- Inlet Diameter: 4"/5"
- Mandrel-Bent Construction: Maximum flow efficiency, helping your diesel breathe easier

How to Choose Your DPF Delete Kit?
4” vs 5” Straight Pipe Comparison
-
4‑Inch Straight Pipe: Best suited for stock to lightly modified trucks; offers a crisp, aggressive exhaust crackle without overwhelming drone; maintains a quieter interior environment for everyday commuting and light hauling.
- 5‑Inch Straight Pipe: Ideal for heavily tuned or competition‑oriented setups; produces a deep, rumbling tone with reduced high‑pitched overtones; maximizes exhaust flow under load, making it the preferred choice for towing, high‑EGT scenarios, and drivers who want a commanding auditory presence
Different Types of DPF Delete
DPF Race Delete
- DPF-only removal for minimal system alteration
- Most economical delete solution available
- Designed for tight budgets or emissions-testing avoidance, not maximum performance gains
Downpipe-Back Delete
- Full replacement from downpipe to tailpipe for unrestricted flow
- Increases torque and throttle response where it matters most on the street
- Perfect for mild street builds that keep the original turbo in place
Muffler vs. No Muffler
With Muffler
- Reduces exhaust noise for improved cabin comfort
- Only 5–10 HP restricted, barely perceptible on the road
- Better chances of passing local sound regulations and inspections
Straight Pipe (No Muffler)
- Bold exhaust note for a commanding auditory presence
- Zero restriction for peak power extraction
- Designed exclusively for track or closed-course use

---tab FAQ---
FAQ
Q1: Does the ECM on 2019+ Ram trucks need to be unlocked before flashing a delete tune?
A1: Yes. Late-model 6.7L Cummins ECMs feature strict factory read/write locks. The ECM must either be bench-unlocked or flashed using a supported late-model tuning interface (e.g., EZ LYNK with unlocked ECM licenses or MM3) before installing this physical delete kit to avoid putting the engine into non-start or limp mode.
Q2: What should I do with the DEF (Diesel Exhaust Fluid) and SCR system components after deleting?
A2: Once you flash the delete tune and install the exhaust and EGR hardware, the DEF pump and SCR (Selective Catalytic Reduction) system are rendered completely inactive. You can leave the tank mounted or remove it entirely. It is highly recommended to drain all remaining DEF fluid from the tank to prevent crystallization and corrosion if you plan to keep the tank installed.
Q3: How does this kit interact with the factory hydraulic lifter engine design used in 2019+ Cummins?
A3: 2019+ 6.7L Cummins engines feature a redesigned block with hydraulic lash adjusters (lifters). Deleting the EGR system prevents heavy soot buildup in the engine oil, which protects the tight hydraulic lifter oil passages from clogging and reduces the risk of lifter ticking or premature valvetrain wear.
Q4: What do I do with the pressure and temperature sensors on the factory downpipe and SCR?
A4: You will unbolt all EGT sensors, NOx sensors, and differential pressure sensors from the factory exhaust system. Disconnect their wiring plugs from the chassis harness and secure the vehicle-side plugs with weather-proof tape or zip ties. The custom delete tune disables these sensor circuits in the ECM logic.
Q5: Do I need to modify the factory intake throttle valve when installing the EGR delete?
A5: When installing the EGR block-off plates, the factory intake throttle valve assembly remains in place or is bypassed depending on your chosen plate configuration. Your tuner will set the throttle valve to remain in the 100% open position electronically to ensure unrestricted airflow into the intake manifold.
Q6: Can this delete kit be completely reversed to return the truck to stock?
A6: Yes. This kit is a direct bolt-on and clamp-on modification that utilizes factory mounting locations and rubber exhaust hangers. No permanent cutting or frame welding is required on standard wheelbase configurations, allowing all OEM emissions hardware to be reinstalled if necessary.
