I have read a few articals on exhaust systems. I see alot of 10hp gains with a good free lowing exhaust buy getting headers and free flowing mufflers. not sure about Turbos they do say that a free flow system will give you some increase but the nubers all depend on the turbo, intake, Blow off, WGA and a few other factors. But they all agree that it does improve perfromance.
