Believe it or not, FL used to have emissions testing. I lived through it. They abandoned testing after a comprehensive independent study concluded that the amount of pollution caused by the vehicles waiting in line to be tested and being tested on the rolling dyno or idling caused more pollution than the centers were removing by rejecting failed vehicles.
That same study would probably apply to any state. Emission testing is ridiculous.
In the end, I passed testing with my race car (needed to pass just so I could race in "street classes") by swapping carburetors and doing the test running on alcohol. It was fun watching the test takers eyes water and ask me to pull out of the building. They, very reluctantly, failed me on the visual inspection since I had zero emission equipment (other than hollowed cats), but passed me because the sniffer test was spotless.
FL never had the inspection requirements like CA that require CARB certification. They just required that cars had catalytic converters and could pass the sniffer test. If they didn't like the car, they would then also require a rolling dyno test with the sniffer.
Edited to add...this time around I chose to go with PPE catted downpipes. I don't have emissions testing where I live, but am trying to make up for my past. It could take a long time. LOL
