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

 

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).    

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:

The turbo would certainly remove most pulse stress, and drop the temps; so
could be fine.  Yes, I think 200 hours would be a success - I don't expect
the .065" 321 SS internals of my secondary muffler to last that long.

 

Nice clamps.  Maybe that and some of that exhaust repair stuff that comes in
a tube to seal things up.

 

Best,
