They also make a quad-tipped version of this diffuser, for either the standard Cyba quad tips or the larger Bastuck quads.

I never saw them as fake vents but I guess I can see that now. I think what makes the is diffuser look great is that the two diffuser slats/strakes are perfectly defined and tightens up the rear of the car greatly.
