Salt won't crack stainless all by itself.

The middle-of-weld cracks in the first pic are probably due to residual stress, not filling the weld enough, or using the wrong filler metal for the application. It's a localized stress problem.

Judging by how the weld metal is all piled up in one spot and the other piece is completely disconnected (the resonator in the 2nd to last pic) I would say that one is a lack of fusion. It's not like it broke, it just never really fused and stuck. So it came apart on that seam.

What's even more exciting is that *everyone else who has this exhaust* will probably have this problem, as well. it's not like they had one rogue welder grab some half-assed filler metal to do the welds on JUST YOUR EXHAUST.

Other people who own this thing should be checking theirs.

edit: Gotta say, as big as some of those cracks are... I can't believe they aren't leaking. I mean that 2nd to last pic it's COMPLETELY UNCOUPLED. What the hell.
