The 6.7 Powerstroke DPF Delete Pipe engine is a reliable powerhouse found in Ford Super Duty trucks. While it delivers exceptional performance in stock form, many enthusiasts and heavy-duty users consider upgrading their exhaust systems with a Diesel Particulate Filter (DPF) delete pipe. A DPF delete involves removing the factory-installed filter to enhance performance and efficiency. This article explores the benefits, considerations, and best delete kits for the 6.7 Powerstroke.
What Is a DPF Delete Pipe?
The DPF is part of the emission control system that traps and burns soot particles produced by the diesel engine. Although the DPF helps meet tough emission standards, it might constrict exhaust flow resulting in decreased performance, increased backpressure, and potential maintenance.
A DPF delete replaces the DPF with an either straight pipe or free flowing exhaust part, allowing unrestricted flow through this exhaust part; however this modification usually requires remapping the ECU and clearing codes to avoid it malfunctioning.
Advantages of 6.7 DPF Removal
Performance:
Without DPF, the reduction of the backpressure ensures free passing of exhaust gasses resulting in considerable enhancements of torque and horsepower outputs.
Turbo spool time is often improved, which can provide better throttle response.
Improved Fuel Economy:
Less back pressure allows the engine to run more efficiently. In many cases, fuel economy improves as well. Some users report 1-3 MPG gains after DPF deletion.
Lower Maintenance Costs:
DPF systems have to be regenerated periodically in order to burn off accumulated soot. This process consumes additional fuel.
A clogged DPF may be expensive to repair or replace. Eliminating the DPF eliminates all of these concerns.
Louder and More Aggressive Exhaust Note
A DPF delete pipe produces a louder and more aggressive exhaust note, which many diesel enthusiasts find appealing.
Legal and Environmental Considerations
It’s worth noting that deleting the DPF is illegal for on-road vehicles in many regions, including the United States, under the Clean Air Act. Vehicles modified with a DPF delete may fail emissions inspections and result in significant fines if driven on public roads.
However, DPF deletes are usually used in off-road or competition vehicles where emissions compliance is not required. Make sure you know the local regulations before doing this modification.
Best DPF Delete Kits for 6.7 Powerstroke
When choosing a delete kit, it is important to select one that has quality components and a compatible tuner for optimal performance. Here are some of the top options:
Flo~Pro:
Flo~Pro- known for durable, high-performance DPF delete pipes offering perfect fit. Flo~Pro kits are often sold complete with all hardware needed to install.
Diamond Eye Performance: Robust and reliable exhaust systems are designed to help optimize the performance gains while at the same time being rather easy to install.
H&S Performance:
H&S- They have tuners that provide a good option alongside a DPF delete in their exhaust solutions.
MBRP: MBRP brings the best quality to their exhaust components with consideration towards durability and improved sounds
RaceME:
Specializes in diesel tuning and delete kits, providing complete remedies for DPF removal
Installation and Tuning
Installing a DPF delete pipe requires mechanical skills and professional tuner calibration of the ECU. Tuning disables all sensors and systems associated with the DPF to negate error codes and maximize engine potential.
Conclusion
A 6.7 Powerstroke DPF delete pipe is the upgrade for unlocking the ultimate potential in trucks, be it for off-road or a competition, since it significantly improves the performance, efficiency, and sound of it. Of course, considering the legal and environmental impact is needed. When you do proceed, though, a premium-quality delete kit from the best brands will give it a more durable and long life. Always consult local laws and professionals to make informed decisions about your vehicle modifications
