The MagnaFlow 23004 is a direct-fit underbody catalytic converter that restores factory emissions performance and keeps the check engine light off. It uses a spun OE style body sealed by a single laser fusion weld to reduce leak points, 16 gauge 409 stainless steel mandrel-bent tubing, and 410 stainless barbed hangers for a low-mass, thermally efficient design. Installation is bolt-on with the included gaskets and hardware, no cutting or welding required. It interchanges with OE part 18160-RMX-A00.
