Havent heard any such noises with my C6.  See if  your exhaust is
rubbing against something ;  ill bet youre getting a vibration somewhere
Let us know.

Hi all,

I keep hearing noise fro            m the back (underneath) on my 2000
Coupe.  The nois    e is upon take off from about 15 mph to about
35-40 mph.  The sound is similar to coins inside a tin can (rolling on
floor).

While washing the car over the weekend, I sprayed the back
bottom side and hit the mufflers whic            h had a similar
sound.  Could it be that one of them is loose?  My worst case fear is
the rear-        end/differential, but I do not note a difference in
performance (the take off).

       I'll be looking underneath for loose parts this weekend, but
thought         I'd post to see if anyone h    as experienced s
omething similar.

In front of the rear axle on both exhaust pipes there is a flange
connection, may be loose, doubtful. In front of those, in the middle,
under the drive shaft, is a spring loaded suspension bracket for both
pipes, check that. That's if it is a stock muffler setup, if it's an
aftermarket set they have slip joints that do come loose above the
swing axles.
