A lot of guys seem to believe that inlets and exhausts are about gas flow. I would say one thing - sound waves do not like going around corners, and in a port they do not behave like laminar flow. The shape of a supersonic jet aircraft fuselage is not always what might be expected. A Norton Commando cylinder head might work better if it was on back to front.
