Atlanta, GA Emissions Testing

Hey guys, I haven't had a modded car for a few years but I know we used to be able to get away with catless cars if there was no CEL.

I was wondering if anyone was running catless and still passing in the Atlanta counties that require emissions as long as they have a tune keeping the lights off. I saw there were some changes Jan 2021 from the "clean Air force"

Thanks!

You won't pass in Atlanta with the codes turned off because your cats will not register as 'ready'. One not ready equals a fail. You either have to reinstall the old cats and get the emissions to a ready/passing status or find an o2 sim and do the same with that device. In the bmw world they are called downpipe fixes. Not sure if there is one for the f80.
