Description

This 5" downpipe-back exhaust system is designed for page-listed 2019–2024 Ram 2500 / 3500 6.7L Cummins diesel applications. It starts behind the factory downpipe and replaces downstream exhaust sections where compatible.

This system is listed as a DPF / CAT / SCR delete-style exhaust product and may remove, replace, or alter factory emissions-related exhaust components depending on the vehicle configuration. Compatible tuning, calibration, or supporting modifications are required before operation. Final fitment, sound, exhaust flow behavior, temperature behavior, drivability, and performance results may vary depending on vehicle condition, tuning, cab / bed configuration, exhaust layout, installation quality, and supporting components.

What Is a DPF and Why Is It Used?

A Diesel Particulate Filter (DPF) is part of the emissions system found on many modern diesel vehicles. Its job is to capture soot and particulate matter from the exhaust before it exits the vehicle.

Depending on driving habits, operating conditions, and mileage, a DPF system can gradually become restricted as soot accumulates. Over time, this may affect how the vehicle operates and how often maintenance is required.

Common signs associated with DPF-related restrictions can include:

Frequent regeneration cycles

Warning lights or reduced performance modes

Increased exhaust back pressure over time

Maintenance or replacement considerations on high-mileage vehicles

About DPF Replacement Components

DPF-related exhaust components are typically intended for specific use cases such as off-road applications, racing vehicles, export markets, or as part of a complete emissions system service or replacement process.

These components are designed to work with compatible exhaust configurations and should only be installed and used in compliance with applicable local, state, and federal regulations.

Important Notice

Products in this category are intended for off-road, racing, or closed-course use where emissions laws apply. They are not represented as street legal, emissions-compliant, CARB-compliant, or legal for use on public roads unless explicitly stated.

DPF delete, CAT delete, race pipe, or related diesel exhaust products may remove, replace, disable, or alter emissions-related components, including but not limited to DPF, catalytic converter, SCR, DOC, EGR, sensors, or related factory systems. Compatible tuning, calibration, or supporting modifications may be required to avoid engine codes, limp mode, regeneration issues, or drivability problems.

Professional installation is recommended. Buyers are responsible for verifying vehicle compatibility, local regulations, emissions requirements, sensor configuration, exhaust layout, and any required tuning or supporting modifications before purchase and installation.

Performance gains, sound changes, airflow changes, temperature changes, fuel economy changes, reliability results, fitment, and drivability results may vary. No specific performance gains, fuel economy improvements, or long-term reliability results are guaranteed.

DPF Delete & Race Pipe FAQs

What is a DPF delete pipe? +
A DPF delete pipe is an exhaust component designed to replace or bypass the factory Diesel Particulate Filter section on compatible diesel vehicles. Product design and included components vary by SKU, vehicle platform, exhaust layout, and emissions configuration.
What is the difference between a DPF delete pipe and a CAT delete race pipe? +
A DPF delete pipe relates to the Diesel Particulate Filter section, while a CAT delete or race pipe may relate to the catalytic converter section or a combined emissions-related exhaust section. Some products replace multiple factory components. Always check the product title, fitment table, package list, and installation notes before ordering.
Do DPF delete products require tuning? +
Compatible tuning or calibration is typically required when the DPF, catalytic converter, sensors, or related emissions components are removed, replaced, disabled, or altered. Without the required supporting calibration, the vehicle may trigger warning lights, engine codes, limp mode, regeneration issues, or drivability problems.
Are DPF delete pipes street legal? +
DPF delete, CAT delete, and race pipe products may alter or disable factory emissions-related equipment and are generally intended for off-road, racing, or closed-course use where emissions laws apply. They are not represented as street legal, emissions-compliant, CARB-compliant, or legal for public road use unless explicitly stated. Buyers should check applicable regulations before purchase and installation.
Will a DPF delete increase horsepower or torque? +
Horsepower, torque, throttle response, towing performance, and exhaust gas temperature results are not guaranteed. Results vary by vehicle condition, tuning, installation quality, fuel, turbo setup, exhaust configuration, supporting modifications, and use case.
Will a DPF delete improve fuel economy? +
Fuel economy changes are not guaranteed. Any change depends on tuning, driving style, load, gearing, vehicle condition, tire size, exhaust configuration, and supporting modifications. No specific MPG improvement is promised.
Will a DPF delete trigger a check engine light? +
It may. Removing, replacing, disabling, or altering DPF, CAT, SCR, DOC, sensor, or regeneration-related components can trigger warning lights, engine codes, limp mode, or drivability issues without compatible tuning or calibration. Always verify the required supporting calibration before installation.
Is a DPF delete the same as an EGR delete? +
No. A DPF delete relates to the Diesel Particulate Filter section of the exhaust system, while an EGR delete relates to the Exhaust Gas Recirculation system. Some vehicle builds may involve multiple emissions-related components, but each product should be verified by its own fitment, package list, and tuning requirements.
Can I install a DPF delete pipe myself? +
Installation difficulty varies by vehicle and exhaust layout. DPF-related exhaust products may involve rusted hardware, heavy exhaust sections, sensors, clamps, flanges, tight underbody clearance, and required tuning or calibration. Professional installation is recommended.
Does every DPF delete kit include the same parts? +
No. Package contents vary by vehicle and SKU. Some products may include a single race pipe, while others may include clamps, hangers, adapters, sensor provisions, gaskets, or related hardware. Always check the product photos, package list, and fitment notes before ordering.
What should I verify before buying a DPF delete or race pipe? +
Verify your year, make, model, engine, emissions configuration, exhaust layout, pipe diameter, cab and bed configuration, sensor setup, tuning or calibration requirements, included components, and applicable regulations before purchase.
