2007.5-2009 Ram 6.7L Cummins All-in-One Delete Kit | DPF & EGR & CCV
Unlock the true power and efficiency of the first-generation 6.7L Cummins with our comprehensive All-in-One Delete Kit for the 2007.5-2009 Dodge Ram 2500/3500. This package is specifically designed to eliminate the restrictive factory emissions systems that cause soot buildup and reduced engine life. By removing the DPF and bypassing the EGR cooler, you allow your Cummins to breathe clean, cool air, resulting in immediate performance gains.
Whether you choose the updated V2 Mini Maxx, this kit provides a complete hardware and software solution to transform your truck into a reliable, high-performance machine.
Key Performance Features
-
Choice of Mini Maxx Tuner (V2): Select the industry-standard Mini Maxx platform that fits your needs. Both come pre-loaded with race-ready tunes to deactivate emissions sensors and prevent "Limp Mode" or Diagnostic Trouble Codes (DTCs).
-
4" Stainless Steel Race Pipe: A heavy-duty, mandrel-bent straight pipe that replaces the restrictive, soot-trapping DPF, significantly reducing exhaust backpressure and EGTs.
-
Full EGR Delete & Cooler Bypass: Includes high-flow billet aluminum block-off plates and all necessary hardware to completely bypass the failure-prone EGR cooler system.

Why Upgrade Your Early 6.7L Cummins?
The 2007.5-2009 models were the first to implement heavy emissions hardware, which often led to premature turbocharger carbon build-up and clogged cooling systems. This kit addresses these "weak points" directly, restoring the legendary reliability the Cummins name is known for while unlocking the superior torque of the 6.7L displacement.
-
Substantial MPG Gains: Eliminating "regeneration" cycles typically results in a 3–5 MPG increase.
-
Lower Operating Temps: Preventing hot exhaust gases from re-entering the intake leads to cooler engine operations and cleaner oil.
System Specifications & Materials
Q1: What’s the difference between 4-inch and 5-inch exhaust systems for Ram 6.7L Diesel trucks?
- 4-inch Systems: The "Gold Standard" for stock or moderately tuned Ram 2500/3500 trucks. It maintains the necessary backpressure to optimize low-end torque, making it ideal for daily driving and consistent towing.
- 5-inch Systems: Engineered for high-horsepower builds (500+ HP) and extreme performance. These systems maximize exhaust flow to aggressively lower Exhaust Gas Temperatures (EGTs) and provide the deepest, most aggressive Cummins exhaust note.
Q2: Can a magnet stick to this pipe? Is it genuine stainless steel?
- Yes. This system is crafted from T-409 Stainless Steel. Unlike 304-grade (non-magnetic), T-409 is a magnetic ferritic stainless steel specifically engineered for the high-heat cycles of a diesel exhaust. It offers superior corrosion resistance over aluminized steel and is the industry standard for durability in the "Salt Belt" and humid regions.
Q3: How thick is the exhaust pipe, and what is its expected lifespan?
- The pipe features a heavy-duty 14-gauge (approx. 2mm) wall thickness. Built from durable T-409 stainless, it is designed to withstand the heavy vibrations of the 6.7L Cummins and resist rust and heat fatigue for years of reliable, hard use.
Q4: Does the Ram 3500 DPF Delete Kit come with a muffler?
- We offer both Muffled and Straight-Pipe configurations.Muffled: Reduces in-cab drone, making it the preferred choice for long-distance highway towing.Straight-Pipe: Delivers a raw, aggressive exhaust tone favored by off-road enthusiasts and competition builds.
Performance & Tuning
Q5: What’s included in the Dodge Ram 6.7L Diesel DPF Delete Kit?
- Each kit is a complete bolt-on solution and includes: (2) mandrel-bent exhaust pipes, (2) heavy-duty clamps, (1) secure hanger, and (3) high-strength bolts. No extra components are needed for standard installations.
Q6: What specific performance benefits will I see on my Ram 6.7L?
- By removing the restrictive DPF and CAT, you unlock:Faster Turbo Spool: Quicker throttle response and less turbo lag.Lower EGTs: Critical for protecting engine components under heavy loads.Improved Fuel Efficiency: Significant MPG gains when paired with proper tuning.Reliability: Eliminates DPF clogging and the "Limp Mode" associated with failed regeneration cycles.
Q7: How much MPG gain can I expect on my Ram 2500?
- While results depend on your specific setup and driving habits, many Ram 6.7L owners report jumping from 13–14 MPG (stock) to as high as 18–19 MPG after installation and proper ECU remapping.
Q8: Do I need a tuner for this DPF Delete Kit to work?
- Yes, absolutely. Removing emissions equipment requires a DPF-off tuner (such as EFI Live or EZ Lynk). Without a tune, the truck will trigger a Check Engine Light, enter "Limp Mode," and potentially suffer engine damage.
Installation & Legal Information
Q9: Can I install this kit at home on my Ram 2500/3500?
- Yes. Most owners can complete the installation in about 1 hour using basic hand tools. The direct-fit design utilizes factory mounting points, so no professional lift or specialized shop equipment is required for most models.
Q10: Can I legally drive my truck with this DPF delete kit on public roads?
- ⚠️ WARNING: OFF-ROAD / RACING USE ONLY. Removing the Diesel Particulate Filter (DPF) is a violation of U.S. EPA and CARB emissions regulations. These kits are intended strictly for closed-course competition or non-road use. Using this on public highways can result in significant fines and failed emissions inspections. Always verify your local and state laws.
