I don't suppose we have anyone on this forum that has access to a dyno and the time to check it out. All we need is someone to donate a stock exhaust when they switch out to aftermarket. They could run with the stock pipes, then drill out the partial cc, run again, then get rid of the rest of the cc, and run again. There would be our results on the same bike, with all other factors remaining equal...and a whole bunch of time eaten up by some kind soul...for the benefit of all of us around the world. I think we would all find the results quite interesting.
I'm not saying that I have doubts that there would be some gains, the further the exhaust is opened up, but how much of a gain is the question that needs answered in order to determine just how far someone wants to go in the process. Not everyone on here is going to be willing to do a lot of extra work to gain an unnoticeable 1 or 2 hp. Some will do anything to squeeze every little bit they can, and others will be quite content with what they have if there isn't some sizeable gain.
If I am running with the partial cc removed, and it's proven that removal of the entire cc gets me from 92 hp to 93 or 94 hp, I don't think that I am willing to go to the work of cutting my exhaust pipe apart, removing the rest of the converter, and welding it back together. If we are talking about another 5 to 8 hp, that might be enough of an argument to move more of us to action.
I would think that it would be much easier to get the pipes off a standard 09 model before cutting our apart. There will soon be lots of stock systems sitting in peoples' garages once some of the aftermarket systems hit the market. I'm assuming that the pipes off the 96" are the same size as ours, but just without the cc. If not, then that shoots down my argument.
