Genny flexible exhaust

[g_man1146]

Alan, Yes. The second flex was installed on the vertical section just below the
90 degree elbow. Since the 15K genny in that Bird (Serial # 2) had a water
cooled exhaust manifold that connected the exhaust via studs protruding from the
manifold, there was now enough flex to install or remove the pipe without
disturbing the manifold.

As I recall, thge two flex sections were different diameters but both available
at a local muffler shop.

(As opposed to the flex making the elbow.)

after I purchased it in 1991. This was an "accordion" type about 10-12" long. I
replaced it with two flex connectors, one where the original was and another on
the pipe where it turned 90 degrees. The replacements had a stainless woven
appearance. Doubling up seemed to do the trick. They were still fine when I sold
the coach in 2001. Don Bradner has that coach now and can tell you if they are
still holding.

replacing that thing.
