MagnaFlow California Grade Right Secondary Catalytic Converter - Ford F-150 / Lincoln Mark LT 5.4L 2006

MagnaFlow 4651695 is a direct-fit replacement for the right side underbody catalytic converter, built on 16 gauge 409 stainless steel tubing with a ceramic substrate, 308 stainless MIG welds and a single laser fusion weld that replicates the OE joint and reduces the chance of a leak. It carries CARB Executive Order D-193-189, so it is legal for use in California and CARB restricted states on the listed vehicles, and MagnaFlow developed it from 3D scans of the original part so geometry and sensor ports match. The assembly measures 48in overall with a flanged inlet, a pipe connection outlet, two sensor ports and OE sized 410 stainless barbed hangers, and one Torca AccuSeal clamp is included in the box.
