If you go to this link it says Top Secret has side vortech generators in carbon or kevlar and "center mount" vortech generators on carbon or kevlar.
Does anyone know what the center mount vortech generators are or have a pic?

 

I would think its only the center piece of the diffuser rather than the center piece and the 2 pieces on the sides

 

That makes sense
