The Walker CalCat 84175 is a direct-fit catalytic converter built to meet California CARB standards, carrying Executive Order D-182-72. It bolts on in the factory location with OE-style flanges and hangers, so no cutting or welding is needed on the vehicles it lists for. That CARB approval is the main reason to pick it over cheaper 49-state converters, which cannot legally be sold or installed on California-registered cars. It suits owners of covered OBDII and older non-OBD vehicles who need a compliant replacement that fits like the original.
