Stand to be corrected but 95dBm springs to mind as the track limit at our local Snetterton circuit. My M3W with MMC stage 1 pipes did pass test on a residents track session but I was ultra gentle on the throttle innocent

BTW I have a free app, Sound Meter, on my Android phone that records and displays dynamic sound levels in dBm. Not sure how accurate mind.
