GT Haus states these 400-cpsi catalytic converters are designed to meet EPA standards, not CARB. They are not legal for use on vehicles registered in California (California Vehicle Code Sections 27156 and 38391). Federal law prohibits tampering with emissions-control devices; check your local inspection rules before ordering.
