Your Ford Mustang is relatively new, and we'll assume it has been relatively taken care of. It should not have a problem passing the California emissions test. It's true, there is a difference with California legal and Federal legal emission requirements. And, for the most part California is stricter. However, a used vehicle, such as your Ford Mustang (which has not had its emission components modified) can pass the California smog inspection process.
If you'd like to have an emission test administered in Florida (only for the purpose of ensuring its emission results are passing - you'll need to get a California Smog Check in order to register your Mustang in California) and look up California emission cut scores, we've attached the California Emissions Cut Scores link below. The tested emissions are HC, CO, and NO.
