What is the loudest exhaust

[Ferruccio]

Mind you, Sport and Corsa modes will get you same loudness. Otherwise, Strada - valves closed, Sport/Corsa - valves open. That's all.

Thats not exactly correct. Even in Corsa and Sport, valves remained closed below ~3000-3500 RPM and only open after.

I beg to differ.
After the car goes for a minute, or so, through the initial start up mode, while parked.
Strada mode - subdued.
Sport mode - growling, much deeper though.
Corsa mode - growling (the same loudness as Sport mode).
Not fighting you, but can you check the loudness and get back with your findings?
