The analysis re exhaust is correct. However, peak HP is controlled by max boost. There is no way holding open the exhaust flap is making more power. Perhaps there's a slight reduction of back pressure reducing turbo lag, but I doubt it's enough to feel.

The louder exhaust note is just fooling your mind.
That's right, N63 is regular turbines. Fast enough as is, so I am still happy.
