Well the first part i cant answer as i dont know and i found it on Ebay.
Your question so to speak answers my own.
So how much it dampens sound depends on the baffle? Your question requires me to investigate more about these mufflers then. :wink:
I looked at Youtube and it's at the loud side but not worse than those i already have.
Thanks, your question opened my eyes or in this case my ears. :mrgreen:

No baffle, (almost) no damping.

This part looks just like a tube.
The direction to the bottom may give some improvement so it won't be that loud from directly behind any more. But I would not expect a significant reduction of the sound level without any baffle in there.
