No Packing, Kelly.  Basically concentric tubes with holes in them.  It appears to use acoustical wave damping as a primary sound suppression technique followed by damping from the energy lost caused by  the numerous holes.  The HushPower  resonator is basically 1/2 of the regular HushPower II muffler (also 1/2 its length)
