..... are the 197's (57k miles) prone to exhaust baffles breaking or coming loose? Car is standard and seems to be the center section in question.

I am pretty sure this is the issue I have, just cant seem to find an awful lot of documentation of this issue really, many threads just seem to fizzle out with no end/outcome
