I have a 4", turbo-back exhaust and I hear that hissing sound when I am near the exhaust exit. I assume it is the turbo. BTW, it changes tone if you remain at the exhaust exit long enough. Sorry I couldn't help more.

I too, think it might be normal. My son's 03 Dually does it. Think you can prove it by having someone else shut of the engine while you stand at the tail pipe. Engine will shut down in a few revolutions, while the turbo can be heard to roll on for a bit. Let us know after you've tried it.
