This exhaust configuration replaces the factory DPF section with a race-pipe assembly for selected Ford 6.7L Powerstroke trucks. The listed 4-inch 2011–2017 race-pipe configuration is intended for Ford F-250 and F-350 6.7L Powerstroke diesel trucks. Other selectable configurations differ by pipe diameter, model-year label, exhaust coverage, and muffler option, so select the required configuration before ordering.

Listed fitments only. Check the selected configuration, the truck’s factory emissions layout, and the existing exhaust system before installation. Suspension lifts and other vehicle modifications can affect exhaust alignment and may require installation adjustments.
| Material | T-409 stainless steel |
|---|---|
| Material Thickness | 2 mm |
| Available Pipe Diameters | 4 inch or 5 inch, depending on the selected configuration |

T-409 stainless steel is magnetic; a magnet sticking to the pipe does not by itself indicate that the material is ordinary carbon steel.
The DPF is part of the factory diesel exhaust aftertreatment system. Installing this race pipe removes the applicable factory DPF exhaust section and replaces it with a straight-through pipe assembly. This mechanical change also affects the sensors and control strategies used for emissions monitoring and DPF regeneration.
This product does not delete, block, or reroute the EGR or crankcase ventilation systems. It is not an EGR delete kit, CCV reroute kit, or DPF-back exhaust.
4-inch 2011–2017 race-pipe configuration:
Package contents vary by selected configuration. Components differ between race-pipe, muffler, and downpipe-back versions. Check the selected configuration before installation.
Tuning and programming are not included. A compatible DPF-delete-capable calibration is required as part of this exhaust-system conversion. Match the tuning device and calibration to the truck’s model year, engine control system, and installed exhaust configuration.
Without the required compatible programming, emissions-related sensors and DPF regeneration logic can trigger diagnostic trouble codes, illuminate the check engine light, or prevent the truck from operating as intended.
View the listed tuner option. Tuner compatibility must match the vehicle and selected exhaust configuration.
Professional installation by a technician familiar with diesel exhaust aftertreatment systems is recommended.

Emissions and road-use notice: This product alters factory emissions-control equipment. Installation can affect emissions testing, vehicle registration, manufacturer warranty, and insurance coverage. Intended race-use labeling does not override federal, state, or local law. The owner and installer are responsible for ensuring that the vehicle’s configuration and use comply with all applicable requirements.
A1: It replaces the applicable factory DPF exhaust section with a race-pipe assembly. It does not modify the EGR or crankcase ventilation system.
A2: The listed configuration covers 2011–2017 Ford F-250 and F-350 trucks with the 6.7L Powerstroke diesel engine.
A3: It is a mechanical exhaust configuration. Tuning, programming, and electronic modules are not included.
A4: That configuration includes two exhaust pipe sections and one exhaust clamp. Other configurations have different components.
A5: No. A compatible tuning device and calibration must be obtained separately.
A6: Yes. The mechanical change affects emissions-related sensors and DPF regeneration logic, so compatible programming is required as part of the conversion.
A7: Yes. Incompatible or missing programming can trigger emissions-related diagnostic trouble codes and a check engine light.
A8: The selected pipe diameter and component layout differ. Choose the diameter and style that match the truck’s exhaust configuration rather than selecting by diameter alone.
A9: A muffler-equipped configuration adds a muffler to the exhaust assembly to moderate exhaust sound. Package contents and model-year labels differ by selection.
A10: Yes. Suspension lifts, non-stock exhaust parts, altered hangers, and previous exhaust work can affect alignment and clearance.
A11: Yes. Installation involves removing factory exhaust hardware, disconnecting emissions-related sensors, aligning pipe sections, and checking for leaks.
A12: Yes. Removing factory emissions equipment can affect all four. Applicable federal, state, and local requirements must be considered before installation.
