You know what, I can't really see a single area in the pics that is a certain failure point except for the suspicion that the warping in the pipe wall before the bifurcation may be a sign of metal that has stretched (weakened) under heat and air loads during the hot start - but I can't also say that I know the pics really show the whole picture either - it is inconclusive. There was a thread a while back on the debate points of weather a wet/hot start is dangerous for further use of a pipe. It seems it was about one to two years back. A lot of very informative information. Do a search and see that thread. You may find some information on that thread that may convince you to either keep the pipe in the jet, or replace it. I wish I could give you more information. All my pipes have been straight pipes, I've never used a bifrucated pipe - so that is a further complication that I can't offer insight on.
