Help with exhaust flange

Off the batt sorry for the rookie question. I'm trying to start getting my exhaust on my rat rod figured out. I have s300 and need exhaust flange and v band so I can weld it to the exhaust. I'm not sure what to buy bc I haven't seen my size that I need. ID is 3 7/16

OD is 4 5/8. Any guidance would be helpful.
