Grummy and I discussed this at the May Meet.
I was randomly selected for a noise level test at a race meeting a couple of months back. The bike has a full Micron race system. They tested at 8Krpm and gave a verdict of 95dB.
Do the track day organisers state the RPMs they test at?
I personally believe that track day /club race officials don't know what they're doing with the meters......Grummy was tested at 103dB with a stock pipe and can, I was tested at 95dB with a full race system.
I'm pretty sure by the 98dB limit, they mean "road systems only", but it doesn't sound as shit...... bearing in mind, they'll want the day to run as quietly as possible to stop the complaining neighbours.
