2007.5-2012 6.7L Dodge Ram Cummins 4" CAT&DPF Delete Pipe
Unlock the peak performance of your 2007.5-2012 Ram 2500 or 3500 with our premium 4" DPF Delete Pipe. Specifically engineered for the early 6.7L Cummins Diesel, this high-flow solution replaces the restrictive factory Diesel Particulate Filter (DPF). By eliminating this massive bottleneck, your engine breathes freely, runs cooler, and delivers the raw power and torque the 6.7L platform was designed for.
Constructed from heavy-duty T-409 Stainless Steel with a 2mm wall thickness, this system is built to survive extreme heat and harsh road conditions. The mandrel-bent design ensures maximum exhaust velocity, providing a deeper tone and significantly better engine response.
Key Performance Benefits
-
Massive Fuel Economy Gains: By removing the restrictive DPF and ending power-robbing "regen" cycles, most owners report an increase from 13–14 MPG up to 18–19 MPG combined.
-
Lower Exhaust Gas Temperatures (EGTs): Reducing backpressure pulls heat away from the turbocharger and engine top-end, essential for maintaining reliability during heavy towing.
-
Instant Turbo Spool-Up: Experience noticeably faster throttle response and smoother power delivery by removing the primary exhaust flow restriction.
-
T-409 Stainless Steel Durability: Our industrial-grade 2mm thick stainless steel offers superior thermal resistance and structural integrity compared to cheaper aluminized kits.
-
Eliminate Costly Maintenance: Stop worrying about DPF clogging, sensor failures, and expensive emissions-related repairs that lead to "Limp Mode" and high service bills.

- 4"Turbo-Back Fitment: 2010-2012 Dodge Ram 2500/3500 6.7L Cummins Diesel.
-
Tuner Mandatory: A DPF-Delete capable tuner is required. Removing the DPF without an ECU remap will trigger "Limp Mode" and diagnostic trouble codes (DTCs).
-
Hardware Included: Includes necessary clamps and hangers. Minor cutting may be required for specific shorter wheelbase (cab/bed) configurations.
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.
