Thanks Al, I agree it seems awful thin. However, I will be using it downstream of the Turbo (and after a foot of 321 pipe).  I want to use it to absorb vibration, movement and expansion on the way to the new muffler that I am installing (flowmaster).  Also, rumor is that it worked for Tracy to go from his header to muffler.  The turbo should soften things up even more....
 
If I get 200 hrs out of it between replacement, I would consider that a success.  Although I may want to think of a new way to attach it rather than having to weld it on every 200 hrs.  Something like this clamp may be an option:
 
 

Dave ;

I wouldn't expect much from this stuff – it's only .010" wall thickness.  It may be fine on a rotary if far from the ports; and maybe downstream from a muffler.  Otherwise the temperatures and the pulses would likely destroy it.

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?
