Obviously, this is an issue unrelated to this specific discussion and can be saved for another thread...unless of course, you are among those who believe that 2.75" exhaust is responsible for power-loss.
Regardless, the setup on that black Z looks badass. I'm much more a fan of a proper canister-style exhaust aesthetically versus the other offerings. It will certainly be nice to see the results once more of these units get shipped out.
