Found this video of the CTS V Sport and took a special look at the exhaust setup which gives us an idea of what type of axle back muffler arraignment we may see on the C6 Camaro. We have seen through spy photos already a peak at what appears to be the same setup on the hand built prototypes that have been seen so far in public.
Go to 6:02 of the video for a clearer view.

This a view of a 4 cylinder ATS chassis and also a rear view of one the 6 gen Camaro prototypes.
