If your car is modified (Headers, Cam, no Cats, Etc…) how do/did you get it to pass emissions testing in Missouri? This is why I am looking into historic plates. The testing if fairly strict on what will and won’t pass.
Also are you running catalytic converters on your Street Mustangs? Can you get away with not having them on?
It was much easier a few years ago when the laws were less strict!
