2007.5-2012 6.7L Dodge Ram Cummins DPF Delete Race Pipe 4"

This product family includes three 4-inch exhaust configurations for Ram 2500 and 3500 pickup trucks equipped with the 6.7L Cummins turbo-diesel engine. Choose a 2007.5-2012 Cat & DPF replacement pipe, a 2007.5-2012 DPF Delete Race Pipe, or a complete 2010-2012 turbo-back exhaust. Each option is made from 2mm-thick T-409 stainless steel. These products do not fit Cab & Chassis models or trucks equipped with factory or aftermarket air-ride suspension.

Product Overview

This listing includes three distinct exhaust products that replace different sections of the factory exhaust system. Select the configuration that matches your truck’s model year and the section you need to replace for improved exhaust flow and reduced exhaust restriction.

The 4-inch Cat & DPF Delete Pipe is designed for 2007.5-2012 Ram 2500 and 3500 pickups. It replaces the factory section identified by the product name as the catalytic converter and diesel particulate filter section while retaining the remaining exhaust components.

The 4-inch DPF Delete Race Pipe is also designed for 2007.5-2012 applications but is listed as replacing the DPF section rather than the longer Cat & DPF section. Its exact connection points should be compared with the factory exhaust before ordering.

The 4-inch Turbo-Back Exhaust is available only for 2010-2012 models. It begins at the turbocharger outlet and replaces a larger portion of the factory exhaust than either replacement-pipe option.

All three configurations use mandrel-bent T-409 stainless steel tubing with a listed 2mm wall thickness. Actual exhaust sound and vehicle response vary by configuration, vehicle condition, engine calibration, wheelbase, and installation.

Key Features

Three Distinct Exhaust Configurations: Choose a Cat & DPF replacement pipe, a DPF Delete Race Pipe, or a complete turbo-back exhaust based on your vehicle and replacement needs.

Model-Year-Specific Turbo-Back Fitment: The turbo-back system is designed only for 2010-2012 Ram 2500 and 3500 pickups.

4-Inch Exhaust Tubing: All listed configurations use 4-inch tubing for a consistent exhaust diameter through the replacement section.

T-409 Stainless Steel Construction: Built from T-409 stainless steel for durability and heat resistance in diesel exhaust applications.

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

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

Designed for Smoother Exhaust Flow: The replacement pipes are designed to reduce restrictive exhaust routing through the sections they replace. Actual results vary by truck and configuration.

Available Options

These three options are not interchangeable:

• The Cat & DPF pipe replaces a longer emissions-related section than the DPF Delete Race Pipe.
• The DPF Delete Race Pipe is a shorter replacement configuration based on its listed product type.
• The turbo-back option begins at the turbocharger outlet.
• The turbo-back option does not fit 2007.5-2009 models.
• No muffler or exhaust-tip options are listed.

Compare the product images, pipe length, bends, connection ends, and mounting points before selecting an option.

Installation Notes

Professional installation is recommended to verify correct routing, alignment, and clearance around the frame, suspension, drivetrain, fuel tank, and body.

The original product information estimates approximately one hour for installation with basic hand tools. This is an estimate rather than a guaranteed installation time. Actual installation time depends on the selected product, vehicle condition, corrosion, wheelbase, existing modifications, equipment, and installer experience.

Minor pipe trimming may be required for certain shorter-wheelbase or cab-and-bed configurations. Assemble and test-fit all pipe sections before making permanent cuts.

The supplied information does not confirm whether welding is required. Verify whether the selected option uses fully clamped connections or requires welding.

Some factory clamps, hangers, fasteners, or mounting components may need to be reused. Keep all removed factory hardware until installation is complete.

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

Frequently Asked Questions

Will these products fit my 2007.5-2012 Ram 2500 or 3500?

The Cat & DPF pipe and DPF Delete Race Pipe are listed for 2007.5-2012 Ram 2500 and 3500 pickups with the 6.7L Cummins engine. The turbo-back option is limited to 2010-2012 models.

What is the difference between the Cat & DPF pipe and the DPF Delete Race Pipe?

The Cat & DPF pipe is designed to replace the factory Cat and DPF section. The DPF Delete Race Pipe is listed as replacing only the DPF-related section. Compare the pipe length, bends, and connection points before selecting an option.

What is the difference between a replacement pipe and the turbo-back system?

A replacement pipe changes only a specific section of the existing exhaust. The turbo-back system begins at the turbocharger outlet and replaces a larger portion of the factory exhaust.

Does the turbo-back system fit a 2007.5-2009 truck?

No. The turbo-back option is listed only for 2010-2012 Ram 2500 and 3500 pickups.

Does any option include a muffler or exhaust tip?

A muffler and exhaust tip are not confirmed in the supplied product information. Check the complete package contents before ordering.

Will I need to cut the exhaust pipe?

Minor trimming may be required for certain shorter-wheelbase configurations. The exact requirement depends on cab style, bed length, wheelbase, existing exhaust layout, and the selected product.

Is welding required?

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

Are clamps and hangers included, and does this fit Cab & Chassis trucks?

Clamps and hangers are listed as included, although some factory hardware may need to be reused. These products do not fit Cab & Chassis models or trucks with factory or aftermarket air-ride suspension.

Is a DPF delete pipe legal for street use?

These products are intended for off-road and competition use only where permitted. Always verify compliance with local, state, and federal regulations before purchase or installation.

Does a straight pipe delete the DPF?

A straight pipe may replace factory exhaust sections, but fitment depends on the exact product and connection points. This listing includes a Cat & DPF replacement pipe, a DPF Delete Race Pipe, and a turbo-back exhaust—not a universal straight pipe.

Is DPF delete good for engines?

Results depend on the vehicle, calibration, and use case. This product is designed to reduce exhaust restriction in the sections it replaces, but actual performance varies.

Compliance Notice

These products are 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.
