Magnaflow 13-17 Lexus LX570 5.7L Direct Fit Converter

Replacing a catalytic converter on a 2013-2017 Lexus LX570 or Toyota Land Cruiser means finding a unit that matches the factory exhaust routing exactly. MagnaFlow part number 5582633 is a CARB-compliant direct-fit converter that does just that, using OEM-matched dimensions developed through 3D scanning so the converter drops into the factory mounting points.

Construction uses 16 gauge 409 stainless steel tubing with mandrel-bent passages to maintain smooth exhaust flow. The spun body is joined with a single laser fusion weld, and all other joints use 308 stainless steel MIG welds. Two flat ring gaskets come in the box to seal the connection points, which means you can avoid reusing old corroded factory gaskets during installation.

Note that this is part number 5582633, which is a companion part to MagnaFlow's 5582632 for the same vehicle range. They serve different positions in the exhaust system, so verify which converter position you need before ordering. This unit is legal for sale in all 50 states and meets California Air Resource Board requirements.
