I agree, however the sound pressure is not only reduced, but chopped to bits and "over written" by the whizzing sounds. This topic is not intended to be another "how to make it louder" general topic though. It is about if we can get some semblance of a naturally aspirated sound by extracting the sound from the exhaust headers before it crashes like waves on the shore into the turbo. A simple analogy is screaming into a fan. The fan chops up the sound of your voice. What if we put a microphone between you and the fan?

Any scientific evidence for this?
The fact that the discrete pressure waves coming out of the exhaust ports
do exist before they hit the tubine - whether even fire or not - and we have evidence in the form pulse tuned exhaust employed in F1- these pressure waves must produce a crisper, better sound than what we hear coming out of the exhaust pipe. Agreed?
What does this sound like?
Are there echos back fromt he turbine?
That sort of thing.
