2013-2018 6.7L Dodge Ram Cummins DPF Delete Race Pipe

This product family includes multiple exhaust configurations for 2013-2018 Ram 2500, 3500, 4500, and 5500 models equipped with the 6.7L Cummins turbo-diesel engine. Available options include a 4-inch Cat & DPF replacement pipe, 4-inch downpipe-back systems, and 4-inch or 5-inch turbo-back systems. Selected configurations are available with a muffler. Each option is constructed from 2mm-thick T-409 stainless steel. These systems do not fit Cab & Chassis vehicles, and additional bed-length, suspension, and wheelbase restrictions may apply.

Product Overview

Choose the exhaust configuration that matches the section of the factory exhaust system you need to replace.

The 4-inch Cat & DPF Delete Pipe replaces the factory exhaust section identified as the Cat and DPF section while retaining the remaining exhaust components. It is not a complete downpipe-back or turbo-back exhaust system.

The 4-inch Downpipe-Back Exhaust retains the factory downpipe and replaces the exhaust from the downpipe connection toward the rear of the truck.

The Turbo-Back Exhaust begins at the turbocharger outlet and replaces a larger portion of the factory exhaust system. Turbo-back configurations are available in 4-inch and 5-inch diameters, with separate short-bed and long-bed options where specified.

Muffler-equipped options are designed for customers who prefer a more controlled exhaust tone during daily driving, towing, or work-truck use. Non-muffled configurations produce a louder and more direct exhaust sound. Actual sound and vehicle response vary by truck condition, engine calibration, wheelbase, and selected configuration.

Key Features

Multiple Exhaust Configurations: Choose a Cat & DPF replacement pipe, downpipe-back exhaust, or turbo-back exhaust based on the section of the factory system being replaced.

4-Inch and 5-Inch Options: The 4-inch configurations provide a practical balance of clearance and exhaust volume, while the 5-inch turbo-back options use larger tubing and generally produce a deeper exhaust tone.

Muffled and Non-Muffled Versions: Selected configurations include a muffler for a more controlled sound. Options without a muffler provide a louder and more direct exhaust note.

T-409 Stainless Steel Construction: T-409 stainless steel is designed to withstand the heat and demanding conditions associated with diesel exhaust applications.

2mm Wall Thickness: Heavy-duty 2mm tubing provides a solid structure for off-road, competition, towing, and work-truck applications.

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

Designed for Improved Exhaust Flow: The larger, smoother exhaust path is designed to reduce restrictive exhaust flow and support consistent exhaust movement. Actual results vary by vehicle condition, calibration, and configuration.

Available Options

These configurations replace different sections of the factory exhaust and are not interchangeable.

• A Cat & DPF pipe replaces only the identified Cat/DPF section.
• A downpipe-back system retains the factory downpipe.
• A turbo-back system begins at the turbocharger outlet.
• Short-bed and long-bed systems use different pipe lengths or layouts.
• Only options specifically labeled “with Muffler” include a muffler.

No exhaust tip is confirmed in the supplied product information.

Installation Notes

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

The original product information describes these systems as bolt-on configurations and estimates approximately one hour for installation with common hand tools. Actual installation time varies based on the selected system, vehicle condition, corrosion, wheelbase, existing modifications, and installer experience.

Minor trimming may be required for certain wheelbase configurations. Always test-fit all exhaust sections before cutting or permanently modifying a pipe.

Short-bed and long-bed turbo-back systems use different pipe lengths or layouts. Select the correct bed-length option before installation.

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

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

Frequently Asked Questions

Will this fit my 2013-2018 Ram truck?

It is designed for listed 2013-2018 Ram 2500, 3500, 4500, and 5500 models equipped with the 6.7L Cummins engine. It does not fit Cab & Chassis vehicles. Fitment also depends on bed length, wheelbase, suspension, and the selected exhaust configuration.

What is the difference between the Cat & DPF, downpipe-back, and turbo-back options?

The Cat & DPF pipe replaces only the factory section identified as the Cat and DPF section. A downpipe-back system retains the factory downpipe and replaces the exhaust behind it. A turbo-back system begins at the turbocharger outlet and replaces a larger portion of the exhaust.

How do I determine whether my truck has a Short Bed or Long Bed?

Check the factory build sheet, window sticker, VIN-based vehicle specifications, or owner documentation for the original bed length.

You can also measure the inside of the cargo bed from the front bed wall to the inside of the closed tailgate. A short bed is generally approximately 6 feet 4 inches long, while a long bed is generally approximately 8 feet long.

Do not select the bed length based only on cab style. The same cab configuration may be available with different bed lengths and wheelbases. Confirm the exact bed measurement before selecting a turbo-back option.

Should I choose a 4-inch or 5-inch system?

The 4-inch configurations provide a practical balance of clearance, exhaust volume, and sound. The 5-inch turbo-back systems use larger tubing and generally produce a deeper exhaust tone. Actual sound varies by truck configuration and muffler selection.

Which options include a muffler?

Only configurations specifically labeled “with Muffler” include a muffler. Non-muffled options use a more direct exhaust configuration and generally produce a louder tone.

Will the system require cutting?

Minor pipe trimming may be required for certain wheelbase configurations. Test-fit the complete system before cutting. Installation requirements may differ between Cat & DPF, downpipe-back, and turbo-back options.

Is welding required?

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

Are clamps and hangers included?

Yes. Clamps and hangers are listed as included. Some factory hardware may need to be reused, and exact package contents may vary by configuration.

Does this fit Ram 2500 trucks with factory air-ride suspension?
