Rattling noise coming from exhaust
I need some help....I have a loud rattling noise coming from the middle area of the underside of my car (around the bends of the exhaust) It happens when I rev my car in neutral as well as at speeds...What could this be? YOur help would be much appreciated.

This is surprisingly a common problem that Mercedes still hasn't made efforts to resolve. The catalytic converter comes apart internally, the broken pieces inside are what you hear rattling around.

it is a weird noise, it happens only when the car has warmed up, under 2k rpms, and on and off throttle. I checked out were the sound was coming from and it sounds like alot farther up the line then the cat, but I could be wrong....it sounds like a large rock inside the exhaust...only and example of course.
Thanks

The car has 4 catylatic converters. They are all located within about 2 ft of the engine. You are probably looking at the resonator, which lies between the cats and muffler.

Unfortunately my car just went off of warranty a couple thousand miles ago. Can you tell me approximately how much it would cost to fix this problem? Should I have the dealer do it or a muffler shop?
thanks,
thanks,
