Hi,

The sleeve in the muffler that the pipe from the Cat goes into had some
broken welds on it.  Additionally, the bracing brackets to the edge of
the muffler had some broken welds as well.  I was just having them patch
things together (band-aid) until next year when I am seriously
considering putting in a stainless exhaust.

Cheers,
Steve W.
