Think about the hot-air connections on old VW (bug) defrosters off the
exhaust shroud.

Or maybe the flex-line that conducts hot air from exhaust manifold shroud to
the automatic choke on older (carbureted) auto engines?

I'm looking for a source of 1 1/2" flexible exhaust tubing. Mild steel is
acceptable. I want to use it for a model of the headers of a tuned
exhaust for my 0320 Lycoming engine that I have mounted in my Baby Belle
helicopter. The idea is to have 4 equal length pieces attached to exhaust
flanges bolted to the cylinders, arrange the 4 pieces to intercept the
4-into-1 collector, coat the tubing with epoxy resin so that the shape is
maintained and then present these pieces to be copied by the exhaust
bender.
