I did / do several traydays at Spa, never had an issue with the dB's
I have a exhaust system with valves whitch I can switch from open exhaust to muflers.
But even with the valves ope, never had a warning from the stewards!

Wow, that's interesting....

Just compared the pictures I took with the ones I took in 2018, I must say it's difficult to spot any...
No, definitely don't dare to use it in my fresh engine.
But was thinking of adding it to my fuel (in also my other cars)
What do you mean by a cup? Cups come in many sizes ;-)
