MagnaFlow's California Grade Direct-Fit Catalytic Converter 5531881 is a CARB-compliant, spun-body converter that keeps the check engine light off while restoring factory emissions performance. It is built from free-flowing mandrel-bent, 16-gauge 409 stainless steel tubing and joined with a single laser fusion weld that mirrors the OE spun-body design to minimize leak points and improve thermal efficiency. The compact, low-mass unit bolts in with no cutting or welding, and the included gaskets seal the connections. It meets or exceeds California Air Resources Board requirements for legal use in California and CARB states.
