I just found this quote on a website talking about cars in Panama (I found it on the web so take it for what it's worth)...
Cars sold in the United States have been required to have catalytic converters since 1975 but that is not the case in Panama...we don’t have any environmental requirements so there aren’t very many catalytic converters or people who can repair them.
