I think we will have to wait a while before Akrops release an exhaust like the one in the top pic.My guess it is an R&D jobbie.
The 'new' twin outlet can was used on Superstock race bikes a couple of years ago.

Ive got a pic somewhere of Frankies spare '04 999 at Misano with such an exhaust.

There ya go.Also note the single sided swingarm.
