There's been a big to-do going on for years about this in the motorcycling community. The short of it is that there is no way that a P.O., using a sound meter, can reliably duplicate the testing conditions on an exhaust system for noise. There are too many other variables that come into play, mainly the testing environment of the street, which is not the lab where the actual testing (for db) is done.
The trick is to not have a 'too loud' exhaust, whatever that is, to avoid getting stopped in the first place.
