California OBDII Direct-Fit Converter

MagnaFlow 5481705 is a California Grade CARB-compliant direct-fit catalytic converter built for the 2004-2005 Ford F-150, left position. It is engineered to replace the original exhaust component with a bolt-on, no-cutting, no-welding installation when used with the proper tools.

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 applications. The MagnaFlow 5481705 uses stainless steel construction, a ceramic substrate, and a spun-body design to match factory packaging and exhaust routing.

Fitment and Product Details

This MagnaFlow catalytic converter is built specifically for the Ford F-150 2004-2005 left-side application listed in the fitment data. The compact, low-mass construction supports thermal efficiency, while the mandrel-bent stainless tubing helps maintain exhaust flow characteristics. MagnaFlow 5481705 is a direct replacement for the original equipment-style converter on the specified Ford F-150 models.

This part cross-references Walker (e.g., 5481705, 5481705) for the same application.

What This Part Helps Address

  • Check engine light caused by catalytic converter efficiency faults
  • Failed emissions inspection on a CARB-regulated vehicle
  • Corrosion-related exhaust deterioration at the converter body
  • Leak concerns at the converter seam or connection points
  • Factory converter replacement on a 2004-2005 Ford F-150, left side

Installation Notes

Install using the proper tools and verify all sensor and flange connections before final tightening. This direct-fit unit uses a bolt-on inlet and clamp-on outlet, and no cutting or welding is required for installation on the listed vehicle applications. Confirm the vehicle’s emissions certification and engine family against the fitment notes before ordering.

Quality Assurance

MagnaFlow uses 3D scanning and metrology during development to match OE fit and function. This converter is designed to meet or exceed California Air Resources Board requirements and has undergone additional testing for legal use in California and other CARB-restricted states on the listed vehicles.
