[C320-list] Muffler leaks and drainage

[Troy Dunn]

Warren et. al.-

We just sent our muffler to CD in November.  The cost of the muffler and
drain valve which is sold separately and which you have to tap your self is
almost $500 by the time you factor in shipping both ways.   We should be
receiving the muffler in the next month or so I suspect.
