Only reason I mention this is DB levels at local racetracks. I had to custom make exhaust tips that point down in order to pass DB levels. I'm lucky my AA exhaust has removable tips.
This is an excellent question as it's most of the reason why a valve system will remain on our car. We do track days too and in the uk the rules for max db are very harsh.
Even some stock cars are not allowed on many of the tracks we use.
The quiet setting will easily pass on even he most strict tracks over here.
The car will be going to Bedford autodrome which is probably the most strict.
We will make a video of it going round and not being black flagged!
