The MagnaFlow HM Grade direct-fit 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. As an HM Grade converter it meets Federal EPA emissions standards for higher-mileage 49-state vehicles. Gaskets and mounting hardware are included for a bolt-on installation that needs no cutting or welding.
