4" Downpipe-Back Exhaust W/Muffler 2011-2025 Ford 6.7 Powerstroke
$690.00
Modern 2011-2025 Ford 6.7L Powerstroke diesels utilize DPF systems to meet emissions standards. However, these filters can clog over time, increasing exhaust backpressure and reducing fuel efficiency. Upgrading to a 4" or 5" downpipe-back exhaust system eliminates the DPF, reducing maintenance while improving airflow and mileage.

Benefits
Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg.
It removes the need to service the DPF at regular intervals (cleaning, replacement)
A DPF delete will remove the possibility of a DPF failure which could cause expensive diesel repairs
Due to less exhaust backpressure, the DPF delete increases exhaust flow and therefore increases the performance of your motor!
Paired with an ECU remap, the DPF delete is proven to increase power and torque for all vehicles
Many users report that upgrading to a 5 inch downpipe-back exhaust on 2011–2025 Powerstroke trucks results in notable benefits: Quicker turbo spool‑up and smoother throttle response Lowered exhaust gas temperatures (EGT) and reduced backpressure Fuel mileage improvement in real-world tests (~5–10% gain)
