Exhaust leak
That is a bell fitting, just clean the rust off with a wire brush. Paint on a little Anti-Seize to the bell and bolt on the bell flared end of the Exhaust pipe, with it's slide on flange.
Just like this picture, no exhaust doughnuts or flat gaskets to blow out. Mates up nice to whatever angle the exhaust pipe comes in at.
Truck manifold pictured here, but same application.
