The MagnaFlow Direct-Fit Catalytic Converter is a California CARB compliant replacement that keeps the check engine light off on the Ford F-150 3.5L. The stainless steel spun body carries a monolithic honeycomb catalyst behind an OEM-style ribbed heat shield, and a single laser fusion weld with a compact low-mass design resists leaks and warms up quickly. It bolts in with the proper tools, no cutting or welding, and the required gaskets and hardware are in the box.
