I may have the power rating and purpose of this engine wrong.  It is
what another attendee at Racing Beat told me.   The picture shows the
INCONAl exhaust system together with an Inconal bellows.  Inconal is
necessary for extremely powerful  high rpm engines that create
massive heat. Jim Mederer said that SS would not hold up in this
application.   The bellows is necessary to allow differential
movement between different parts of the exhaust system.

  I intend to install SS bellows in my exhaust header pipes before
firing the  engine.   Bellows are made of very thin material only
around .02" thick.   Does anyone know what the maximum temps it is
likely to see at 8" from the port x 6000 rpm?  The melting point of
SS is 2550 degrees, so if the temperature stays below 1600  degrees
it should be o.k.   1600 is bright cherry in color.
