Turbo's don't pull the exhaust out, quite the opposite. The exhaust blows the turbo which is on a common shaft as the compressor, and this bit pushes the inlet mix in.
As far as exhaust gas is concerned, the turbo is in the way. And they certainly don't help cool anything! You seen the heat these things operate at? They often glow red under boost conditions! The compressor being bolted to and on a common shaft as the turbo gets mighty hot.
An incorrectly sized turbo setup is not pleasant, the sizing is much more critical than a proper supercharger, you can easily change the speed of the supercharger and compensate for a size miss match, with turbos you need to change the hot side of the turbo to achieve this, much more spendy than a different size pulley.
