awesome.
in Aus these are the legal methods to check an exhaust dB

or simpler directions:

but in summary, 500mm away from an exhaust at an angle of 45 degrees.
with revs at 4000rpm (for our car), and 3 tests results all within 1dB difference for it to be counted as an accurate result. hope that makes sense.
