I'm off to CC in August, it's a great track.
As a rough guide for the noise test, my DD bike roars in at around 98db for a MSV test, and with the increased revs at Castle Combe it shouts at 102db. Make sure you've got the engine up to temp for the test and sort out some db killers just in case. Then you should be fine.
I'm taking the 996 with 50mm pipes and db killers, but the R6 will be going in the van as a backup.
