Subject: [FlyRotary] Re: 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.   

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?

 

Thanks,
