Ford Freestyle Catalytic Converter - MagnaFlow California Grade CARB Compliant Direct-Fit (2005–2007). A direct-fit replacement designed to restore proper emissions control and keep the check engine light off while retaining factory performance.
This MagnaFlow converter (part 5421024) is engineered to match OE flow dynamics and fit for 2005–2007 Ford Freestyle and Five Hundred applications. MagnaFlow uses 3D scanning during development to ensure accurate fit and a spun-body design with a single laser fusion weld to reduce the risk of leaks. The compact, low-mass construction improves thermal efficiency, and the high-strength 16 gauge 409 stainless steel tubing offers strong corrosion resistance for long service life. This unit interchanges with OE numbers 7F9Z-5E212-B and 5F9Z-5E212-BB and includes the necessary gaskets and hardware for a direct, no-cut installation when the vehicle matches the converter’s CARB Executive Order requirements. Designed and tested to meet California Air Resources Board requirements for the listed vehicles; legal for sale in all 50 states including California, Colorado, New York and Maine when the EO/EFN apply.
