"Most Original" and "restored" are contradictions .... putting any kind of finish on any part of the exhaust bumps you out of the "original" class right away, the exhaust system was rust colored from the showroom floor
and how is anyone going to know if any individual piece of the exhaust is "original" or NOS or NORS or fabricated by a good local exhaust shop? you should be able to have the head pipe you need fabbed at a good shop, using your damaged piece as a sample, if you find an older shop they may even have the pattern on file, but make sure they don't use pipe that wasn't available in '54, like aluminized
