The original appears to be asbestos core with steel overwrap. Whatever that would be closest to in modern would be the choice of material. IMO, thicker would be better. Unless the pipe to manifold junction is very very straight, I'd be concerned that with any misalignment thin material might not have enough give or be able to fill on the wide side and would leak.
