Carven direct fit muffler

[Kissmyace9]

I just put on a Carven Progressive muffler this weekend. I love the sound but, under hard acceleration, there's a (for lack of a better word) slight "ringing" during certain rpms. Anyone else had this issue and if so, what's the fix?

Perhaps a clamp is loose?

I tightened them all pretty dayum tight. It's worth a shot though.
