    In a lot of places a turbo is considered a muffler or sound damping device which allows for exhausts to be straight piped after the turbo legally.

      For a short time I worked in a factory that made school busses. They used big diesel engines and not a single one of them had a muffler. The SCR and the turbo made them plenty quiet.
