Figures are dependent on the Dyno so no use comparing your against Tims graph as it looks like a generous Dyno and your figure of 100 sounds more accurate .
The full system is a big drop of coin for little gain that you would use on the street. Don't get me wrong it's your money and mods are cool, but don't do it expecting power gains as you will be disappointed. If you still want to do it for mods sake then go nuts.
Probably get more power by decking the head and blue printing the engine

In all seriousness having owned a 07 zx6 amongst a few other bikes u wont get alot for a $2K exhaust plus PC plus tune. Seat of your pants dyno will be hard to tell the diff and if anything you may lose some low end torque which in a roadgoing 6 u dont want to do!
I landed the full system for $1150 and got a 2nd hand pc3 so it wasn't too much dollars, but I was going from the original exhaust, you've already got a good slip on.
You could always get some after market headers (or a chop job and a link pipe) to remove the cat, a pc3 and a custom tune for half the money of a full system.
As others have said test riding a 10 might be worth it if you're really after more power....
Nothing wrong with buying a bit of bling Stu but like you said you were chasing HP which obviously alot here have attested that it wont do that much of! But if you have too well theres nothing wrong with a bit of patience on ebay or gumtree. If your lucky a bargain may arise but its rare. Also theres nothing wrong with test rides of bikes at dealers. My only advice there is if u fall for a zx10 buy the same colour, ride home and pretend nothings changed
