Same system at Goodwood Andy... they ask where you change gear on the rev range and test you at that point with a microphone poked up yer spout.
With the C43 in sport Plus mode it would, I suspect, fail.... it is rated at 74dB in comfort mode....and 82dB is the legal limit. It is a lot louder than Tarka, which has rear exhausts and Sports Plus adds a lit of noise. People tend to look....for the idiot in the lowered hot hatch!!
