Inquiring Inmates want to know... so I duly sacrificed and put my pipe to the band-saw for the sake of furthering our knowledge base:

As we can see, it is mostly hollow inside with only very few pieces of metal acting as supports more than baffles... No packing material at all, just a pipe going through the middle with holes in it. I suspect the shape of it acts to dampen the noise before it exits the pipe.

Amazing if you really think about it... a big empty cavity dampening noise rather than amplifying sound waves.

(Ok... I didn't really cut up my pipe. This photo credit properly belongs to 'VtStrom' in the group.)
