I don't feel that way. I don't expect from a beautiful powerful bike that it have a louder sound. It's the performance I am after. I think the sound is perfect for the performance. Louder pipe does not make it perform faster unless designed that way. And I am fine with stock power.
Another factor is I love music when riding for long periods. Good music, the ride, and scenery go together like peanut butter, jelly and white bread for me. Don't want to hear motor while listening.
Actually, when I used to watch boxing did not care Tyson sounded like he inhaled helium, just that he performed.
I used to think the other way not long ago, and feared getting this bike I would miss a louder sound. Concerned vanished.
Small point about the reference you made to that old song, space cowboy that I hated. Just use screen name pls.
