A port gasket seals a headpipe at the cylinder head; the muffler joint gasket belongs at a different connection. The port gasket is sold individually, so plan the order around the ports being serviced. The linked genuine Honda collar is mounting hardware, not another version of either gasket.
The MAC megaphones are replacement mufflers for the stock F-model headpipes. They are a different purchase from a complete exhaust system. If a previous owner fitted aftermarket headers or changed the connections, confirm the actual arrangement before ordering these slip-ons.
