Powerstroke DPF Delete Kits for 6.0L/6.4L/6.7L Engines

Q: Will a 5-inch DPF back exhaust fit my F-250/F-350 without modifications?

Yes, our 5 inch dpf back exhaust 6.7 powerstroke kits are designed as bolt-on systems using factory hanger locations. However, because 5-inch piping is much larger than stock, it sits closer to the spare tire heat shield. We recommend a quick clearance check during installation to ensure no rubbing occurs under heavy vibration.

Q: Is a DPF back exhaust 6.7 Powerstroke purely for sound?

While the primary benefit of a 6.7 powerstroke dpf back exhaust is a deeper, more refined tone and better aesthetics (especially with our 5-inch tips), it also helps lower EGTs at the tailpipe. However, if your goal is maximum power and fuel economy, it should be paired with a full delete pipe.

Q: What is the specific benefit of a 5-inch DPF back exhaust vs. the stock 4-inch pipe?

While a standard dpf back exhaust 6.7 powerstroke (4-inch) is sufficient for stock power levels, upgrading to a 5 inch dpf back exhaust 6.7 powerstroke offers two main advantages: lower exhaust velocity and deeper resonance . The larger internal volume of the 5-inch pipe allows exhaust gases to expand and cool more quickly before exiting, which can subtly lower EGTs at the tailpipe. More importantly for enthusiasts, it produces a much deeper, throatier "rumble" that the restricted 4-inch factory pipe simply cannot match.

FAQs

While results vary based on driving style and tire size, the consensus among 6.7 powerstroke mpg after dpf delete users is a gain of 2 to 5 MPG. This is achieved by removing the "active regeneration" cycle, which uses a significant amount of diesel to heat the filter to 1,100°F+ to burn off soot.

This is a common myth. The exhaust brake on the 6.7L Powerstroke is integrated into the VGT (Variable Geometry Turbo) vanes. Installing a powerstroke dpf delete kit does not disable this feature. In fact, many owners find the exhaust brake feels more aggressive and responsive because the exhaust path is no longer obstructed by a soot-filled filter.
