---tab Description--- Modern 2011-2024 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. Specification Exhaust Material T-409 Stainless Steel, it is magnetic. Thickness 2mm Inlet Diameter 4.0"/5.0‘’ 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) Installation Estimated install time: ~1 hour with basic tools; faster on a lift. Short-bed or cab‑chassis trucks may require minor cutting/trimming. Kit includes clamps, hangers, and hardware—some OEM pieces may be reused. Tuner Required: DPF, CAT, SCR, and DOC deletions disable emissions sensors. A tuner with Powerstroke DPF delete capability ensures no check-engine lights or fault codes.

A turbo-back replaces the entire exhaust from the turbo, offering more performance but requiring more modification. Q2: Will this 5” downpipe-back exhaust fit a cab & chassis model?A2: No, this kit is designed for standard pickup configurations only (F-250, F-350, F-450). It is not compatible with cab & chassis models due to differences in frame and exhaust routing. Q3: Will the 5-inch exhaust system cause excessive drone inside the cab?A3: The 5" system may produce deeper tones and mild drone depending on cab insulation and presence of a muffler. For a quieter ride, choose the version with a muffler. Q4: Does...
