well then thank your lucky star I am not the one prosecuting the case
It is not that hard to look up any of the information you mentioned when we know (thanks to EPA) what the stock OEM noise values (noise pollution is under their umbrella) are.
btw
don't forget
just like a cop can estimate speed and cite you for that and it WILL hold water in court, they can do the same on noise too. Just because it did not happen once does not mean it won't in the future either. Just consider yourself lucky.
on a sidenote: you FL boys been happy as a pig in shit with no inspections so far. Only been less than 15-16 years since they did away with it. I remember because I was there when it was taken away
but that was when Fl was way in the Black $ wise. Such is not the case anymore.
