I have a two bolt pattern on my exhaust. But unfortunately I don't know the size or is it's doughnut gasket or not. If someone could please help me ... Thank you for your time.

Thanks for the images they help. There is no donut like the older cars had, there is a bell made into the exhaust manifold that connects to the flange of the exhaust pipe. It looks like the exhaust pipe has broken and will need to be replaced by a muffler shop. Please check the images below to see what I am talking about; the nut size is 15mm deep well socket.
