I have the Akra slip-ons / silencer and not the full system. Even with the db killers in place there is no way it will pass the noise test at the track. However, all the events organisers know that the Panigale won't pass the test on standard cans and are a little lenient. Here's how the noise test typcially goes:
Marshall: Its going to fail.
Me: I know
Marshall: Lets test it in any case:
Me: Ok
Marshall: Yep, its 108db. Go and see the organisers.
Me: Ok.. trundle off down pit lane to the office. Hello, I have a Ducati that has failed the noise test.
Organiser: Is it a Panigale?
Me: Yes
Organiser: They all fail
Me: Yes, I know, even with stock exhausts they fail.
Organiser: Go out on your sighting lap and we will moniter. If we flag you, come in.
Me: Ok. Proceed out on sighting lap, make sure revs are low passing the trackside microphone.
Get on with the day.
