When you say you set the valves "loose" how loose ?

They should be .003"/.005" and I would adjust to the .003"

It's possible a baffle broke loose inside the muffler which if moving around randomly could restrict exhaust flow which would cause a sound like you described.

Take the muffler back off shake it around and see if it rattles, Tap it a little and shake again. Try blowing air through it to see how much flow you have.
