2019-2025 Ram 6.7L Cummins DPF Delete Race Pipe 4" & 5"

2019-2025 6.7L Dodge Ram Cummins 4" & 5" DPF Delete Race Pipe

This product family includes multiple exhaust configurations for 2019-2025 Ram 2500 and 3500 pickup trucks equipped with the 6.7L Cummins turbo-diesel engine. Available options include two 4-inch Cat & DPF replacement pipes with different bend designs, plus 4-inch and 5-inch downpipe-back systems with or without a muffler. All configurations are constructed from 2mm-thick 409 stainless steel. Cab & Chassis models are excluded.

Product Overview

Choose the exhaust configuration that matches your truck’s factory configuration, pipe diameter, and preferred exhaust note.

The 4-inch Cat & DPF Delete Pipe options replace the factory exhaust section identified as the catalytic converter and diesel particulate filter (DPF) section while retaining the remaining exhaust components. Two different bend configurations are available for 2019-2025 applications. Although both versions share the same advertised model-year range, their pipe shapes are different and should be matched carefully to the original exhaust layout.

The Downpipe-Back Exhaust options replace the exhaust system from the downpipe connection toward the rear of the truck. These systems are available in 4-inch and 5-inch diameters, with muffled and non-muffled configurations.

Each system is made from mandrel-bent 409 stainless steel with a listed 2mm wall thickness. The smooth tubing design is intended to support maximum flow efficiency and reduce restrictive exhaust flow under load.

Key Features

Multiple Exhaust Configurations:
Choose between a 4-inch Cat & DPF replacement pipe or a complete 4-inch or 5-inch downpipe-back exhaust system.

Two Cat & DPF Pipe Designs:
Two separate 4-inch Cat & DPF pipes are available with different bend configurations. Select the version that matches your truck’s original exhaust routing.

Muffled and Non-Muffled Options:
Selected configurations are available with a muffler for a more controlled exhaust tone or without a muffler for a more direct sound.

409 Stainless Steel Construction:
The listed 409 stainless steel material offers good heat resistance and durability for diesel exhaust applications.

2mm Wall Thickness:
Heavy-duty 2mm tubing provides a solid structure for demanding truck and off-road use.

Mandrel-Bent Tubing:
Smooth bends help maintain a consistent internal diameter through curved sections of the exhaust.

4-Inch and 5-Inch Diameters:
The 4-inch systems provide a practical balance of clearance and exhaust volume, while the 5-inch downpipe-back systems offer larger tubing and a deeper exhaust character.

Available Options

The two 4-inch Cat & DPF Delete Pipe options are separate products. They have different pipe bends and should not be treated as interchangeable. Compare the selected product image, pipe shape, connection ends, and factory exhaust routing before ordering.

Muffler-equipped options are generally better suited to customers who prefer a more controlled sound during daily driving or towing. Non-muffled versions provide a more direct and aggressive exhaust tone. Actual sound varies by truck configuration, wheelbase, engine calibration, and the remaining exhaust components.

Technical Specifications

Vehicle Fitment

Fits:

• 2019-2025 Ram 2500 pickup
• 2019-2025 Ram 3500 pickup
• 6.7L Cummins turbo-diesel engine

Does not fit:

• Ram Cab & Chassis models
• Downpipe-back options do not fit Ram 2500 trucks equipped with factory air-ride suspension

Additional fitment notes:

• The two 4-inch Cat & DPF pipes use different bend configurations.
• Match the selected pipe to the truck’s original exhaust shape and connection points.
• Fitment may vary by cab style, bed length, wheelbase, suspension, and existing exhaust configuration.
• Shorter-wheelbase trucks may require pipe trimming during installation.
• Confirm the selected option before cutting or modifying any exhaust components.

What’s Included

Depending on the selected configuration, the package is listed as including:

• Exhaust pipe sections
• Exhaust clamps
• Mounting bolts
• Exhaust hangers
• Muffler on options specifically labeled “with Muffler”

Some factory mounting hardware may need to be reused.

The inclusion of an exhaust tip, gaskets, reducers, adapters, or sensor-related fittings is not confirmed. Package contents may vary between configurations.

Installation Notes

Professional installation is recommended to confirm proper alignment, connection, and clearance around the frame, suspension, drivetrain, and body.

Shorter-wheelbase trucks may require trimming of one or more pipe sections. Always test-fit the complete system before cutting.

The supplied information does not confirm whether welding is required. Installation method may vary by configuration, so verify whether the selected option uses clamp-on connections only.

Some original clamps, hangers, fasteners, or other factory hardware may need to be reused. Do not discard the original exhaust components until installation is complete.

The original listing estimates approximately one hour for installation with common hand tools. Actual installation time varies depending on the selected configuration, vehicle condition, corrosion, wheelbase, existing modifications, and installer experience.

Changes to factory emissions-related exhaust components may require compatible vehicle calibration. Confirm all vehicle requirements with a qualified professional and verify legal compliance before purchase or installation.

Frequently Asked Questions

Will this fit a 2025 Ram 2500 or 3500?

Yes. The advertised fitment covers 2019-2025 Ram 2500 and Ram 3500 pickup trucks with the 6.7L Cummins engine. Cab, bed, wheelbase, suspension, and exhaust-layout restrictions still apply.

What is the difference between a Cat & DPF pipe and a downpipe-back system?

A Cat & DPF pipe replaces only the factory exhaust section identified as the catalytic converter and DPF section. A downpipe-back system replaces the exhaust from the downpipe connection toward the rear of the truck.

Why are there two 4-inch Cat & DPF Delete Pipe options?

The two pipes use different bend configurations. They are designed to match different original exhaust layouts and should not be treated as duplicate or interchangeable products.

How do I select the correct Cat & DPF pipe?

Compare the option images, pipe bends, connection ends, mounting locations, and original exhaust routing on your truck. Confirm the correct version before ordering.

Which options include a muffler?

Only options specifically labeled “with Muffler” include a muffler. Non-muffled options use a more direct exhaust configuration.

What is the difference between the 4-inch and 5-inch systems?

The 4-inch systems provide a practical balance of clearance and exhaust volume. The 5-inch downpipe-back systems use larger tubing and generally produce a deeper exhaust tone.

Will I need to cut the pipe?

Shorter-wheelbase configurations may require trimming. The exact amount depends on the cab style, bed length, wheelbase, and selected exhaust system.

Is welding required?

The supplied information does not confirm whether welding is required. Verify the installation method for the selected configuration before installation.

Does the package include installation hardware?

The original product information lists clamps, bolts, and hangers. Some factory hardware may also need to be reused. Exact package contents may vary by configuration.

Does this fit Cab & Chassis trucks?

No. The supplied fitment information excludes Cab & Chassis vehicles.

Does the downpipe-back system fit Ram 2500 air-ride trucks?

No. The downpipe-back configurations are not listed as compatible with Ram 2500 trucks equipped with factory air-ride suspension.

Is a DPF delete pipe legal for street use?

Emissions laws vary by location. This product is intended for off-road and competition use only where permitted, so check local, state, and federal regulations before purchase or installation.

Does a straight pipe delete the DPF?

A straight pipe is not the same as a properly matched Cat & DPF replacement or downpipe-back system. Choose the configuration that matches your truck’s factory exhaust layout.

Compliance Notice

This product is intended for off-road and competition applications where permitted. The purchaser and installer are responsible for confirming compliance with all applicable federal, state, and local emissions, inspection, registration, and vehicle-use regulations before purchase or installation.
