To answer your original question, the majority of applications use
larger exhaust tubes to help free up the flow, and wrap the header to
preserve the heat which helps the (hot)gases flow better and maintain
their velocity to the turbine housing, which in turn compresses more
intake charge.

Complicating the system trying to scavenge the exhaust with additional
systems would be more complicated and expensive than getting
better/modifying heads.

It is always better to have good flow through the system. If the
heads/valves flow is poor, the turbo won't change that, it will just
build boost pressure faster because of the restrictive air flow. What
you are really doing with a turbo is increasing the compression ratio,
dynamically of course.

The turbo is about as free as you can get for a perpetual motion
machine, but your really utilizing previously wasted heat and gasses to
drive a simple mechanism.


IMHO,
Your opinion may vary,
I reject your reality and substitute my own,
