California catalytic converters are engineered to adhere to the stringent emissions standards established by the California Air Resources Board (CARB), which surpass federal requirements.

Meanwhile, federal catalytic converters meet the Environmental Protection Agency (EPA) standards, which are comparatively less demanding.
