MagnaFlow 5551294 Catalytic Converter

California-Grade Direct-Fit Converter

MagnaFlow 5551294 is a California Grade, CARB-compliant direct-fit catalytic converter built for specific Ford E-Series applications. It is engineered for a bolt-on replacement with no cutting or welding required, making it a practical choice for restoring emissions system function on the 2009-2014 Ford E-150, Ford E-250, and Ford E-350 Super Duty.

Part of MagnaFlow’s Direct-Fit CALIFORNIA OBDII CONVERTERS line, this converter is designed around OE-style fitment and emissions compliance for listed California and CARB-restricted-state vehicles.

Key Features

• Direct-fit catalytic converter for specific Ford E-Series applications
• CARB-compliant California Grade design for listed vehicles
• Stainless steel body and tubing for corrosion resistance
• Ceramic substrate for emissions control performance
• Spun-body construction with a single laser fusion weld to reduce leak points
• Mandrel-bent tubing for smooth exhaust flow
• Bolt-on inlet and clamp-on outlet for straightforward replacement
• Mounting hardware, clamps, and hangers included
• Oxygen sensor locations: pre-converter and midbed

Product Details

MagnaFlow 5551294 uses a compact, low-mass spun-body design that mirrors the original equipment layout for the listed Ford E-150, Ford E-250, and Ford E-350 Super Duty models. The stainless steel construction helps resist corrosion, while the ceramic substrate supports emissions conversion in a direct replacement format. MagnaFlow’s 3D scanning-based development process is used to match OE fit and function more closely, helping the converter install cleanly on the intended platform.

This part cross-references Walker 16395 and Eastern Catalytic 40294 for the same application.

Common Problems This Part Can Address

• Check engine light caused by a failed catalytic converter
• Emissions test failure on CARB-regulated vehicles
• Exhaust leaks from a worn or cracked converter body
• Corrosion-related damage to the factory converter assembly
• Poor exhaust flow from a deteriorated substrate

Installation Notes

Fits 2009-2014 Ford E-150, N/A. Fits 2009-2014 Ford E-250, N/A. Fits 2009-2014 Ford E-350 Super Duty, N/A. Confirm engine family and CARB Executive Order details before installation, since fitment is tied to the listed emissions certification. Use the included mounting hardware, clamps, and hangers with the proper tools for a direct replacement installation. No cutting or welding is required when installed on the correct application.

Quality Assurance

MagnaFlow designs this converter to meet or exceed California Air Resources Board requirements for the listed vehicles and to comply with CARB guidelines for legal use in California and other CARB-restricted states. The OE-style spun-body construction, stainless steel materials, and laser fusion weld are used to support fitment accuracy and leak resistance.
