The MagnaFlow Direct-Fit Catalytic Converter is a California Grade, CARB-compliant spun-body converter that replaces the factory close-coupled unit with no cutting or welding. It pairs free-flowing, mandrel-bent 409 stainless steel tubing with a ceramic substrate and a single laser-fusion weld to reduce leak points, and carries two oxygen sensor ports for correct pre-converter and midbed readings.
