MagnaFlow OEM Grade Manifold Catalytic Converter - Toyota Highlander / Sienna 3.3L 2004-2007

The MagnaFlow OEM Grade manifold catalytic converter replaces the worn factory unit to restore proper emissions performance and keep the check engine light off. It is built from high-strength 16-gauge 409 stainless steel with mandrel-bent tubing that follows the OE flow path, and a spun OE-style body closed by a single laser fusion weld to reduce potential leak points. The close-coupled manifold design bolts to the cylinder head in the factory location. As an OEM Grade converter it meets Federal EPA emissions standards for 49-state (non-CARB) vehicles. Gaskets and mounting hardware are included for a bolt-on installation that needs no cutting or welding.
