The MagnaFlow California Grade Direct-Fit Catalytic Converter is a CARB compliant emissions replacement that restores factory exhaust flow and keeps the check engine light off. It is built on a spun stainless steel body with free-flowing mandrel-bent tubing and a single laser fusion weld that reduces leak points, plus a compact low-mass design for faster thermal light-off. High-strength 16-gauge 409 stainless steel construction resists corrosion for long service life, and the converter installs directly with no cutting or welding required. This converter meets California Air Resources Board requirements and is legal for sale and use in California and CARB states for the listed vehicles. Gaskets are included for a proper seal.
