Exhaust System: The downtake pipe to the front expansion box has broken up about 3" down from the top flange after 7,405 miles. It does not appear to be burnt thin, the metal has just cracked in all directions above and below the break, and a piece about one inch square has fallen out. We are returning the pipe to you for inspection and are rigging up one of our two spare front expansion boxes to replace it. -------- Rm{William Robotham - Chief Engineer}/IMW.{Ivan M.
