My 999s with Termi can measured 103 at Snetterton last year. Bought some dbKillers to make sure I can get it down to about 100 if need be...
749R with 57mm full system varies between 104 and 107dB. Killer required for Brands evenings and GP circuit.
748R with a 996sps 50mm full system with race cans was 101.5db on Tuesday and I was warned I might get black flagged. I started the day at 100 db. Andy
