Hi, I haven't found a lot of pictures online, just trying to know which one of both has better ground clearance since where I live the roads suck and speedbumps are huge, my Z is on stock suspension and money ain't really a problem.

 

I have the AP single with stock suspension and I've gone over some rather large speed-bumps, very rarely have I hit the exhaust itself. In my experience, if I ever high-center on something it's ~85% of the time the rear "W" brace or the worst case the transmission.
