Just looking into some track days and wondered if anyone has had a 12C noise tested yet?
E.g. The noise limits at Bedford Autodrome in the UK are 101dB(A) static (measured 0.5m from the exhaust at a 45’ angle at ¾ maximum revs) and 87.5 dB(A) drive-by at 20 metres - the drive by points are usually coming out of hairpins under max revs.
