2013-2022 6.7L Cummins 4" CAT/DPF Delete Racepipe for Ram 3500/4500/5500 Cab & Chassis

2013-2022 6.7L Cummins 4" CAT/DPF Delete Racepipe

This Vigor Diesel 4" CAT/DPF Delete Racepipe is designed specifically compatible with the 2013-2018 Dodge Ram 2500/3500 equipped with the 6.7L Cummins diesel engine. As a Racepipe, it only replaces the mid-section of the exhaust system, not the entire exhaust path—making it the simplest, cheapest, and most straightforward DPF/CAT delete solution.

What Is a Racepipe?

A racepipe is the simplest, most direct, and most economical entry-level solution for diesel exhaust system removal. It only replaces the original DPF (Diesel Particulate Filter) and CAT (Catalytic Converter) assembly in the mid-section, using a 4-inch straight-through pipe to replace the original dense filter structure. It allows for quick modification and performance release without replacing the entire exhaust system.

Core Positioning

👉 Simplest / Cheapest / Most Direct

• Only replaces one section of the mid-section assembly, no need to remove the turbocharger.
• Simple installation, lowest cost, immediate results.
• Suitable for budget-conscious users, those needing quick modifications, and those seeking a straight-through sound.

Key Advantages of This DPF Delete Race Pipe

1. Reduced Back Pressure, Smoother Exhaust

The key to diesel engine performance lies in ample cool air. To draw in fresh air, hot exhaust gases must be expelled quickly—but the dense mesh structure of the stock DPF obstructs airflow. Vigor Diesel employs a full straight-through design, optimizing bends and low-resistance pipes to allow exhaust gases to escape rapidly. This:

• ✔ Eliminates exhaust bottlenecks, allowing the engine to breathe more smoothly.
• ✔ Creates space for intake airflow, improving overall ventilation efficiency.

2. Unleashes the Iconic Turbocharged Sound

Stock mufflers and filters not only reduce performance but also kill the soul of a 6.7 Cummins diesel engine—the turbocharged sound. This racing exhaust achieves this by removing all limiting components:

• ✔ Cleaner airflow = faster turbo response.
• ✔ More responsive throttle = louder, clearer turbocharged sound.

How to Choose: Straight Pipe vs. With Muffler

Racepipe (Straight-through)

For those who want a loud sound, a raw, direct experience, and are performance enthusiasts.

Racepipe with Muffler

For those who want a loud sound, but not too noisy, and who want a balance between performance and comfort, and who need to drive long distances.
