Note be careful removing the Nut from the Turbo outlet expansion joint clamp. I tried to remove 2 of those at the Junk Yard and the Nuts were seized onto them and I actually twisted of the threaded portion on one of them and simply gave up on the other.

With that in mind when I did the one at home I had penetrating Oil, a propane torch for heat and a wire brush to clean the thread off before I tried to turn off the nut. If I had to I also had a Nut Splitter to crack the Nut off and simply buy another nut.

I don't have a memory of what I actually ended up doing with it but I know I did not break off the threaded end of the Clamp.
