That would be my best guess also I had the same pro lem with a 01 accord the honey comb just came loose and would rattle when it got going but if it's more of a ticking than a rattle then don't hold me to it haha.

Sounds like the cats are going. Does it get louder/ Is it more noticeable, if you accelerate?
