Simon,
From what you describe, I had a similar problem with a 3-into-1
(one of a pair). I solved it by heating up the whole area until
it was cherry red, then running a L O N G Silfoss rod down into
the cavity from the outside to puddle up the hole.
It worked well, but damn near roasted my knuckles!
My ventures with muffler cement have all been dead losses. In a
short space of time it seems to fracture, and the exhaust shock
waves blow it out. The most effective seals seem to be a mixture
of rust and carbon! ;-)
