It is possible that is could be standard on the Z51 and optional on all other Vettes. I think a couple of other options are like that.

There's going to be HUGE HP potential in this motor, though I'm still curious how the PCM and Active Fuel Management will cope with an aftermarket cam.

. I'll have to hear one before I commit, obviously won't get it if I'm going to swap it out. I wonder how much it will cost?

The dual mode exhaust (RPO NPP) is a stand alone option, it's not part of the Z51 or F55 packages, though it can be added to either. It gets you a whole 6 hp!!! . I'll have to hear one before I commit, obviously won't get it if I'm going to swap it out. I wonder how much it will cost?

It only adds 6hp, but really, on the dyno most other aftermarket exhaust setups aren't going to do much better, and at the sacrifice of a lot of extra noise that make long trips down the highway a head-pounding experience.
Unlike aftermarket exhaust - this exhaust isn't just money down the drain - it will probably allow the Vette to fetch a little more when you go to sell it, whereas most aftermarket mods don't add any value.

Well I look at it this way. If it's only 500-600 bucks, I'd probably do it.

A 3" Corsa setup might cost $1000, or maybe even a bit more. But they have a lifetime transferrable warranty, which I guarantee is at least as good as whatever warranty you might get on the GM system. I also guarantee that Corsa's system will be quiet when cruising and idling, and will sound amazing under acceleration.
