Paul,
After some more thought on the exhaust bracket and header tube - going
the Powersport route is more complex than most builders would
contemplate without ready access to parts. So I thought about the header
tube problem (breaking at the exhaust flange junction) and figured that
the problem could be overcome by using thicker pipe in this are rather
than light tube (compared to flange), welded to heavy flange material.

Even a short section 2" to 3" with a flexible joint after that wouldn't
add too much to the overall weight. One could even go further and weld
small triangular inserts to strengthen the connection from short header
to exhaust flange.

Do you need a drawing?
