There could be an argument that 'coating' the metal inside a chambered muffler with oils and other exhaust crud will cause some sort of sound deadening but it will be minimal.
Most muffler 'break in' people speak is actually the person just getting more used to having a loud exhaust.
OP: I'm disappointed to hear you call it ricerish... I have the regular 2.5" axle back being shipped. I hope it doesn't sound too bad.
Actually, there is a break in period. At least there was on mine. I've had and do have loud exhaust on many cars. I don't need time to get "used" to it. My experience was that upon first installing my AFE axleback, I didn't enjoy the sound it made at lower rpms. I actually intended to remove it.
Life had other plans though and about two weeks later, I get in it, take off and immediately notice the difference. It was much more mild sounding and I liked it. Couldn't believe how much it changed. Now, I'm keeping it.
I understand what you are saying about not having sound damping material. I'm also not pretending to have an explanation (nor do I care). I'm just sharing my own experience.
