I'm planning a trackday at Goodwood in the Aero 8 (series 5 with side pipes). Goodwood have a noise limit of 98Db and I'm concerned that the car will be louder than that. Does anyone know what sort of decibel reading a 4.8 with side exits would make?
I don't.
However I've had cars that have both passed and failed at Goodwood. My suspicion is that side pipes on your Aero will be over the limit. BHM do a track day at Goodwood - why not ask them? They'll know for sure.
