Just curious:
What is the Aussie police procedure for taking dB readings?
What distance from the pipes?
Is the decibel meter "flat", "A", or "C" weighted?
At idle? Or with a throttle twist? Certain RPM?
Mate normally 45 degree angle maybe 10 metres away and a drive/ride by
Also Exhausts have to be stamped with the Aussie approval stamp
No stamp and bike is off the road, like cant be ridden, trailered home??
But unlike Calafornia we still have 2 stroke lawnmowers
