2008 Honda Odyssey - engine too loud

Engine seems much louder than it should be, particularly at highway speeds. Ideas?

Well, by my ear it could be… Wait I can’t hear it and all you told us is that seems louder than it should be. Anything would be a wild guess of a long list of possibilities.

I’d suggest you take it to a shop and tell them what you told us. Let them drive it while you point out the sound you are hearing.
