Donut Gasket On Y-pipe

[tyhuck]

I have decided that my Magnaflow is too loud to try to hunt with, so I was wanting to swap out with the factory muffler, but still be able to interchange between the two (quiet for hunting season, loud for other seasons). I was going to use the factory ball flange at the end of the Y-pipe, but I need to make sure that the gasket inside the flange is reusable. If not, Ill have to make a slip joint and use a band clamp somewhere on the intermediate pipe.

Just for suture reference to anyone wondering, there is no gasket on the flange that connects the Y-pipe to the intermediate pipe.
