The MagnaFlow 49579 is an OEM Grade, Federal/EPA compliant direct-fit catalytic converter that replaces the rear, downstream converter on the 4Runner without cutting or welding. It uses 16-gauge 409 stainless steel with mandrel-bent tubing and OE-sized 410 stainless barbed hangers, and a single laser fusion weld replicates the factory design to reduce leaks. The box includes two flat ring gaskets and one flange gasket. It meets Federal EPA emissions standards for OBDII vehicles and interchanges with OE parts 17450-62040, 17450-62050, and 17450-75020.
