MagnaFlow's California Grade direct-fit catalytic converter is the driver side replacement for the factory unit on the 4.2L V6 F-150, bolting to the original mounting points with no cutting or welding so the check engine light stays off. The body is built from high strength 16 gauge 409 stainless steel tubing with 308 stainless steel MIG welds and OE sized barbed exhaust hangers in 410 stainless steel that resist corrosion and damp noise and vibration. Mandrel bent tubing reproduces the OEM flow path for factory fuel economy and driveability, and a single laser fusion weld replicating the OE design reduces the chance of a leak. It carries CARB Executive Order D-193-103 and ships with the gaskets and hardware needed to install it.
