The backbox of my exhaust dropped, so in taking it off, we found it has two different sorts of mounting rubbers.

The one nearest the rear of the car is the normal one that ALL the ford part sites list as both rubbers, like the one here:

But the second one was different, and apparently is only on the ST from what I can figure out, like the one here:

Not that I'm massively concerned or bothered. Just wondered if anyone knew why?
