Catalytic Converter

welcome to AZ. Tough to fight them on emissions. Best to call the inspection station around 40th street and jefferson I believe. Any ADEQ testing facility should be able to refer you. best to ask the main source for the state, if its not obvious. Might ask MVD if you can get historic plates for it, and skip the BS with emissions.

You can run aftermarket cats though. Not as bad as CA when it comes to having certified equipment. They do a visual inspection to see the cat or cats if you do duals.
