So long story short, I got my car back from the transmission shop and they messed up my exhaust when they had to disconnect it. I've burned ties with this shop, so I'll be repairing it myself. My problem is there's a leak where the green arrow is pointing in the pictures, but I have no idea what it is supposed to look like. Does a gasket or flange belong there? is one end of the pipe supposed to fit into the other? or maybe my pipes are just rusted and need replacing? Any help is appreciated and if anyone has a pic of their setup it would help a lot.
