2019+ 6.7 Cummins DPF Delete Race Exhaust Pipe Overview

Give your 2019-2025 Ram 2500 or Ram 3500 the freer-flowing exhaust path it needs for a cleaner off-road delete setup. This SPETUNER 6.7 Cummins DPF Delete Race Pipe is a vehicle-specific exhaust upgrade for pickup trucks with the 6.7L Cummins diesel engine, using the same fitment model across 2019, 2020, 2021, 2022, 2023, 2024, and 2025 trucks.

By replacing the factory DPF section, this delete race pipe helps reduce exhaust restriction, cut backpressure, support stronger engine breathing, and improve fuel efficiency when paired with the required tuning. Built from high-grade SUS409 stainless steel and offered in 4-inch, 5-inch, DPF Race, DPF Race with Muffler, and DP-back configurations, it is made for Ram Cummins owners planning an off-road build, full delete kit, or performance-focused exhaust system.

Key Features

• Premium Stainless Steel Build: Constructed from high-grade SUS409 stainless steel, offering outstanding corrosion resistance and heat tolerance for lasting durability in extreme diesel exhaust conditions.

Important Notes

• Off-road use only: These products are designed for off-road, closed-course, and race use only. Check the legal regulations that apply where you operate your vehicle.
• Tuning required: A DPF delete pipe is not a standalone “install and drive” change. A dedicated DPF delete tuner is required for ECU tuning to help prevent warning lights and possible engine issues.
• Professional installation recommended: If your build also includes an EGR delete, CAT delete, DPF CAT delete, DEF delete, downpipe, or full exhaust system, confirm compatibility before ordering and have the setup installed by a qualified diesel technician.

---tab FAQ---

FAQ

Q: What does the "DPF race pipe" mean?

A: "DPF race pipe" also called "DPF Delete Pipe", only removes the DPF section and keeps the other parts of the exhaust system.

Q: What does "DP-back/Downpipe-back" mean?

A: This means that the exhaust system runs from the downpipe to the end of the exhaust pipe, replacing everything from the downpipe outlet back. This typically includes the mid-pipe, catalytic converter or CAT section if present, and muffler.

Q: What is the difference between a DPF race pipe and a DP-back exhaust?

A: A DPF race pipe replaces the DPF section. A DP-back system runs from the downpipe outlet back and may replace more of the exhaust path, depending on the selected variant.
