GMPP Exhaust Louvered or Perforated?

Does anyone know if the GMPP performance touring exhaust is the internal louvered straight thru style or the perforated straight thru style?

I am guessing that it is perforated, the resonator has an inner pipe with small holes in it. The muffler isn't too different.

Almost positive its perforated, not louvered.
