My SS flex pipe came from the same source Dave.  Lifespan seems to be inversely proportional to amount of bend in it.   I now use it only for vibration isolation (perfectly straight) and the same piece has been on the plane for over 300 hours.  When I used it for bends I had to replace it in less than 50 hours.
 
 Just got my  20B exhaust system back with Jethot 2000 ceramic coating.  Hope it works as well as it looks.

Subject: [FlyRotary] Flexible Exhaust Pipe.. Tracy?

I just got some flexible exhaust pipe from JC Whitney.  The stuff is pretty neat, it is very flexible (though will not make an extremely tight bend).  It was inexpensive, and made of 304 stainless.  It is also light weight.
 
So the only questions are how well will it hold up, and how to attach it to the rest of the exhaust system. 
 
Tracy, I understand you have been using flexible pipe and it has been holding up OK.  I just want to make sure you are using the same stuff.  Here is the link to what I have:
 
 
Is that the same stuff you are using?  Has it really held up?  My plan for installation is to have u-joint flanges welded on.  Any better ideas or tips?
