What the heck happened to my exhaust?

[Skeek]

As I’m driving down the highway I suddenly hear a rattle and eventually my typical exhaust note sounds a little deeper than usual. After work I climbed under to take a look.

Pipe appears to have corroded shortly past what I believe is the catalytic converter (only one pipe, facing the back end of the Explorer). I would assume someone tried to cut it and gave up, but the irregular wear and corrosion has be perplexed. Any ideas as to what could have caused this?

Common problem unfortunately. Extremely crappy built stock exhaust.

Yeah fair. I remember reading posts about the poor flex piping and catalytic converter, but this seems like such an odd failure point. Not even at the weld to the cat, but a few inches south?

Almost 2 years ago I had them do the fix for the catalytic converter weld recall - figured that would have helped avoid this (hence my thought about a thief with poor follow-through).

Yeah unfortunately the whole exhaust is fail prone. Usually it breaks around the welds, but it is common for it to do it randomly in other places too. Just crappy build quality and materials, lovely Ford sometimes.

Thats crazy.

Sucks. That one side looks a lot worse than the other.

Just put some duct tape on it. Just a flesh wound.
