I used a couple of the free decibel meters on my iPhone as i too didnt want to waste a journey or money.

I coincidently got chatting to a sound engineer at the track day who said a lot of the iPhone ones he finds really accurate.

Only other thing I could suggest is find your nearest track and see if they'll test you for a pack of biscuits lol

And remember to measure at 1.5m and 45 degree's from the exhaust, as that's what they do at the track.

The events I've been to that state they will test at the above 1.5m and 45 degrees when static haven't done so and have just got the meter out at trackside if they think any cars might be a bit loud. 

They have probably got a good idea of the sound levels after doing so many events. 

Always safe to do a check yourself before hand to put your mind at rest  :smiley:

Think the limit was 95 or 98 at Wittering. No body got turned away.

105 is pretty safe like you say
