Description
Product Overview
Eliminate the restrictive factory catalytic converter and Diesel Particulate Filter (DPF) from your 2008-2010 Ford Super Duty with the iFJF 4-Inch Cat & DPF Delete Pipe. The 6.4L Powerstroke's factory exhaust after-treatment system is notorious for creating excessive backpressure, causing regeneration cycles that waste fuel and dilute engine oil. This mandrel-bent T304 stainless steel replacement pipe restores unrestricted exhaust flow, unlocking horsepower, improving fuel economy, and dramatically lowering exhaust gas temperatures.
⚠️ OFF-ROAD / COMPETITION USE ONLY: This product is intended for off-road, racing, and competition vehicles only. Removing catalytic converters and DPFs from on-highway vehicles violates the Clean Air Act. Check local regulations before installation.
Key Features
-
Deletes Both Cat & DPF: Single pipe replaces the entire catalytic converter and DPF assembly in one bolt-on unit — eliminates both major exhaust restrictions.
-
4-Inch Mandrel-Bent Tubing: Full 4.0-inch T304 stainless steel maintains consistent diameter through all bends for maximum flow capacity.
-
Eliminates Regeneration Cycles: No more active DPF regens that waste diesel fuel, dilute engine oil with unburned fuel, and reduce engine life.
-
Massive EGT Reduction: Exhaust gas temperatures drop 200-400°F under load without the DPF restriction — critical for the heat-sensitive 6.4L Powerstroke.
-
Direct Bolt-On Installation: Uses factory exhaust hangers and flanged connections — no cutting, welding, or fabrication required.
-
Corrosion-Resistant: T304 stainless construction withstands extreme exhaust temperatures and resists rust in all weather conditions.

Frequently Asked Questions
Q: Will this fit my 2009 F-350 6.4L?
A: Yes. This pipe fits all 2008-2010 Ford F-250, F-350, F-450, and F-550 Super Duty trucks equipped with the 6.4L Powerstroke diesel. Cab configuration and bed length do not affect fitment.
Q: Do I need tuning with this delete pipe?
A: Yes. Removing the DPF and catalytic converter requires ECM tuning to disable regeneration cycles and prevent diagnostic trouble codes. A DPF/EGR-compatible tuner is mandatory.
Q: Will this stop the DPF regeneration cycles?
A: When paired with proper tuning, yes. The truck will no longer perform active regenerations, eliminating the fuel washdown issue that plagues 6.4L engines in stock form.
Q: Is the 6.4L known for DPF-related issues?
A: Yes. The 6.4L Powerstroke is infamous for DPF regeneration cycles that inject fuel during the exhaust stroke, causing cylinder washdown and oil dilution. Deleting the DPF is a common reliability modification.
Q: Does this affect the exhaust brake function?
A: The factory exhaust brake is controlled by the variable geometry turbo (VGT), not the DPF. The exhaust brake will continue to function normally after DPF removal.
