Ive been to several track days during 2011 and plan to do a few more this year
However whilst my car is a standard 457bhp C63 the db readings appear to be increasing..
a few points
last time out i had to repeat the static test it was just under 98db which was the limit for that day and i received one warning during the drive by readings (limit 96db)
previous sessions have been 105db days so it was no issue and i believe my readings were 94db in static mode in any case
are my silencers becoming less effective ? - ive done 28,000miles
are these tests a little bit approxiamate or even a black art !the tester did comment that weather could affect the reading etc etc
i am not aware of any other C63s struggling with the db limits , some of which are 487bhp or even 500+ bhp
some of the exotica were "lifting" at various parts of the circuit (Goodwood)to keep from infringing
surely im not going to have to do that in mine
Even found some db reducing tubes but doubt they will fit and they seem a bit makeshift
