The rear silencer on my 1997 C200 sounds like a rattle, comes and goes. Presumably the baffles are working loose, needs replacement. Agents charge for the name, probably for units that are also available direct from the manufacturers at half the price. Any comments from other forum members?

Are you asking about the catalytic converter or the muffler? Sounds like a cat problem.

I have heard there is a company in the USA that is rebuilding catalytic converters. Look for Smith Brothers. The biggest fear is buying aftermarket and getting a permanent CEL.

I am almost sure it's a muffler problem, its right in the rear. As far as I am aware the CAT is mounted towards the front, nearer the engine.

You may need to check your exhaust system hangers. These are rubber pieces that hold the pipes and mufflers in place while insulating against shocks and noise.

Should not be too hard to find a muffler, Bosal is a good brand.

Your theory about the baffles coming loose is very likely at this age. If you do a search here and on club202.com you can read about peoples' experience with third party mufflers. Some of them sound too wanna-be/fart pipe for my taste but that is a personal preference thing. Many people put up youtube videos that help you get a feel for the sound of the new mufflers.
