If you look under the passenger floorboard area you will find a braided wire mesh that covers the bellows area. It's main purpose is to allow the engine to move independent of the exhaust pipe. If it has a hole in it I would also expect to see failed regens.

PS Mine was leaking in 2 places and would only smoke during a parked regen. I had no loss of boost pressure as the bellows is after the turbo and all the exhaust has already past the turbo vanes.

Added picture of the bellows pipe.

Nice pics of the exhaust flex piping. I think though, he was referring to the EGR piping that runs across the back of the engine.
