I'm not sure if our Accords have that dumb design in the exhaust manifold downpipe(Y-Pipe).

My Prelude and my friends EF civic had that same problem.

In our cars the exhaust downpipe is 2 pipes in one. Usually the inner pipe breaks off and rattles from around 2k-3k rpm.
If that's the case, take it to a exhaust shop and ask them to cut slits in the pipe and weld the inner one to the outer one...that should stop that damn annoying rattle...we did and it is a pleasurable drive since then

Edit: take a rubber mallet or a hammer with a piece of cloth and bang the downpipe..do you hear that rattle?


Or...maybe your flex pipe has a slight tear?
