Our take on the MagnaFlow Direct Fit Catalytic Converter 05-07 Ford F-Series Rear

This is a direct-fit replacement catalytic converter for 2005-2007 Ford F-250 and F-350 Super Duty trucks with the listed submodels. It bolts on with the included gaskets and needs no cutting or welding, so a driveway install with hand tools is realistic. MagnaFlow builds it from stainless steel with mandrel-bent tubing and 3D-scanned the original to match fit and function. It is Federal/EPA compliant, not California CARB legal, so check your state's rules before buying. Against universal-fit converters, the direct-fit design saves fabrication time and reduces leak risk.

Questions and answers

Is this converter legal in California?
No. It is Federal/EPA compliant only, not CARB approved, so it cannot be sold or installed in California or other CARB states.
Does it fit my 2006 F-250?
It fits 2005-2007 F-250 and F-350 Super Duty trucks in the listed submodels. Check your submodel and emissions system before ordering.
Do I need to weld it?
No. It is a direct-fit unit that bolts to the factory flanges, and gaskets are included.
Will it turn off my check engine light?
It is designed to restore converter function and keep the light off, provided the fault was the converter itself and not an oxygen sensor or wiring issue.
What is in the box?
The converter and the gaskets needed for a proper seal. Reuse or replace your factory fasteners as needed.
How is it different from a universal converter?
A universal unit needs cutting, welding and fabrication. This one is 3D-scanned to match the original and bolts on directly.
