Rattle from mufflers?

[aar0s]

This rattle is driving me nuts only happens when the car is warm and only happens when pulling from a complete stop. It speeds up with the rpm's and only lasts for a few seconds but is loud enough to hear over my flow's. The mufflers are about 8 or 9 years old, could it be something in them rattling after they warm up? Anyone else had a muffler rattle on them?

muffler bearings! LOL Just kidding. I had a flow go bad on me like that too. I hit something onthe freeway and it knocked the muffler good but broke something inside. Got a new one and its all good now.

I would also double check that it's not your ebrake cable clacking on something...i've had this happen several times. It could also be the tail pipes like mine are doing right now.
