I have assumed the Cobrapack and the Powerstick are different in design internally,... is that correct?

Same design louver core & same diameters as with the 2.5" & 3" Powersticks. The Cobrapacks have smooth bodies, so there are no dimples to create sound wave irregularities (or tuning). Also, the larger diameter bodies of the Cobrapacks allow for a larger gap between the core & outer body, which will permit more dissipation of sound. The larger gap also allows for loading of sound deadening materials as an option. Packed mufflers will flow the same as ones without packing.
