Track Day //M + Rpi exhaust decibels?

[Gargybloke]

Anybody done track days with their M with Rpi exhausts fitted and if so do they pass the decibel test ok?

I'm interested in going along to something in the South of England but don't want to fall at the first hurdle after I have paid some money too!

98db on the static tests. Passes most I believe.

Phew! Actually since my post earlier, I found this on zpost which was interesting reading for exhaust geeks.
