2019-2024 6.7L Cummins 4" CAT/DPF Delete Racepipe For Ram 2500/3500

6.7 Cummins DPF/CAT Delete Racepipe for 2019-2024

The Vigor Diesel 4" CAT/DPF Delete Racepipe is a high-performance part that directly replaces the original mid-section exhaust pipe. It's installed in the middle of the vehicle's exhaust system—after the turbocharger's downpipe and before the rear muffler. Its primary purpose is to replace and remove the original diesel particulate filter (DPF) and catalytic converter (CAT) assembly.

This Race Pipe features a large 4-inch straight-through design without any internal filtration, aiming to provide an unobstructed path for exhaust gases from the turbocharger to the tailpipe. It's ideal for those seeking quick modifications, cost-effectiveness, and a straight-through sound.

Advantages of This DPF Delete Race Pipe

Reduced Back Pressure, Smoother Exhaust

The dense mesh structure of the original DPF severely obstructs airflow, creating an exhaust bottleneck. The Vigor Diesel Racepipe features a 4-inch straight-through design, with a low-resistance pipe allowing exhaust gases to escape at extremely high speeds: Real-world testing shows it can reduce exhaust back pressure by up to 80% or more.

Enhanced Horsepower and Torque Potential

By removing restrictive emission components, the engine can operate more efficiently. Based on actual testing, with professional ECU tuning, it can achieve an increase of up to 150 horsepower. Power is readily available for climbing hills, overtaking, and towing.

Reduced Exhaust Temperature (EGT)

Smoother exhaust flow helps dissipate heat more effectively: reducing exhaust temperature by up to 100-180°F, improving overall engine reliability and lifespan.

Size Selection

This product uses a 4-inch pipe diameter, an optimized balance:

• Larger than the original diameter (typically 3.5 inches), significantly reducing back pressure.
• Easier to install than a 5-inch system, avoiding chassis space interference issues.
• Perfectly compatible with 2019-2024 Ram models. 2500/3500 chassis layout
• Offers the best balance between performance enhancement and ease of installation.

Installation and Tuning

Installation Difficulty: Medium (Basic mechanical knowledge required, but professional installation recommended)

Estimated Time: 1-2 hours (faster on a lift)

Installation Steps Overview:

• Park the vehicle on a level surface and engage the parking brake.
• Disconnect the battery negative terminal, ensuring safety.
• Remove the sensors and thermal shield from the original DPF/CAT assembly.
• Loosen and remove the original DPF/CAT assembly.
• Install the Vigor Diesel Racepipe, using the provided clamps and hardware
• Ensure all connections are tightly sealed and leak-free.
• Check that the exhaust hangers are correctly positioned.
• Reconnect the battery and start the test.

Note: For cab/cargo box configurations with shorter wheelbases, appropriate pipe trimming may be required to ensure a perfect fit. All clamps, hangers, and hardware are included; some original equipment hardware may need to be reused.

Tuning Requirements

Tuner Required.

After removing emission control devices such as DPF and CAT, ECU programming must be performed using a compatible DPF removal tuner:

• ✅ Clear fault codes: Prevents engine malfunction indicator lamp (CEL) illumination
• ✅ Optimize fuel injection: Fully utilizes hardware performance
• ✅ Disable regeneration logic: Turns off active regeneration function
• ✅ Improve performance: Achieves maximum horsepower and torque gains
