With 190hrs TT, I noticed a crack on my 360 exhaust.  The crack was where
the #4 cylinder downtube meets the tailpipe. The crack was on the weld on
the back of that juncture, with the crack 1/2 way through the pipe.  I was
always concerned about the fairly long un-supported runs on the two
tailpipes, especially this one.  

My exhaust was coated with Jet-Hot about 5 hours ago; however, I find it
hard to believe this had any effect in that very short time period.  I could
not find anything in the archives and was wondering if anyone has
experienced this problem (and if any modifications were made).
