You'd hear more mechanical noise though any exhaust/headers but think you also hear more turbo spool which wouldn't be bad.

A full exhaust may be better for the GTI as the stock sound is a bit bland/dull and needs a bit better note to it. People may not concentrate on trying to hear a rattle then .
