<DIV>I had the same problem, plus--after working with the header for some time,
it eventually stripped out the aluminum threads inside the exhaust port.
Frustrating, maddening.................</DIV>

<DIV>I used one of those headers and had the exact problem you are
having. In fact, most of the people I knew that used those headers had
the same problem after using them for some time.</DIV>

<DIV>The braid is merely reinforcement for the flexible tubing inside
the braid. My opinion is that that the internal convoluted tubing did
not stand up to repeated flexing from the engine vibrations, eventually
failed, and then started blowing exahust through the braid. I never took
one apart to see inside, though.</DIV>

<DIV>Have a new header - AAP #500 flex header from
Advanced Aero Products I just installed - was
unopened old stock. Old corrugated cooling type
header would back out of the head no matter what -
tried multiple copper washers. I gave up. so
installed new flex header. No backing out, but
motor noise substantially increased. Found that
braided stainless header portion will leak air if I
blow in exhaust end. Anyone familiar with
these flex headers ? Is there something
special I need to do to quiet them down and not leak
? Thanks for any help.
