Its surprisingly noisy and sometimes boomy inside with the hood down
Although my Aero S5 is a very different car, it's also quite noisy.
I fine-tuned the sound with some Dodo matting in the footwells; it's deadened the noise from below, and now I hear the side exhausts from the side B-)
DoDo say that quite small pieces of their foam will quell the noise from a panel. Maybe some judicious use would help hear the right noises from an ARP4?
