From what I've read the CBE is worth ~20 by itself for the top names for the full setup, y pipes, mid, and muffler. FI is at 20, Stillen at 18, etc. Neither system includes test pipes or cats. HFCs are over $500 new from FI, and definitely not counted in the $1,200ish system price. I assume their #'s do not includes test pipes or cats, but could be wrong.
GT Haus is $2,100ish without test pipes or cats.
I've been getting most of my info from here:
370Z Exhaust.com - Sound clips, photos + places to buy
They have dyno #'s on a lot of the setups, but even they don't have GT Haus #'s.
PS: Previous owner of the car got in touch (see earlier in the thread) and says the Meisterschaft system I'm trying to sell/trade only has 3k miles on it. It does look clean still, so I can believe it. Might have some dyno #'s too, but they would include the Stillen G3 intake and tuning, so I'm not sure how valid they would be against what's posted elsewhere.
