expanding foam filler up exhausts

[numtumfutunch]

Out of sheer curiosity has anyone actually heard of this being done, what damage was done and what did it take to fix?

You'd basically have to replace the exhaust system as far as the foam has got in.

Depends on the type of exhaust but in most cases a new back box should be all thats needed.

A carrot has the same effect.

Ouite simply the car won't start, and very hard to detect.

Not that I've tried it myself..........................

I've never heard of that. However, one of the suggested applications for epoxy putty is patching exhausts. Not sure if that was the repair you had in mind.

ETA forgive me as I totally misunderstood the post.
