I pulled mine in one piece about a year ago, I do not think it could be done without a lift and even then by myself it was a pain in the butt.
Later I sold it and had to cut it into three sections for shipping so I wish I had just cut it out anyway
I do not know how long a band clamp will work but they at least make a good temp solution, I have used them on race cars while developing the car and having to take the exhaust off often, once done with development I would weld on V-bands as easier to work with and more reliable overall I am sure, cost a bit though.
