look how to mirror using toribash textures template.
we have box, cylinder and sphere templates
So to flip, you have to invert the faces in the template areas and orientation.
export in gimp as PSD.
In mudbox, go to layers tab, right click->import PSD,
after that you can paint with simetry on in x axis
