From what I understand, is that for every $100 you spend, you get 1 hp. I have an '05 that I have owned since it was new, and was very happy with the way it performed. I came across a deal I could not pass up, and put a LeoVince system on. (Mid-pipe, and can) My requirements were, that I did not want to re-jet the bike, and wanted performance to boot. I got that with this system, and I am very happy with it so far.
I would suggest that you look further into this system to see if re-jetting is required. I personally do not want mess with the carb to make the exhaust work for possible 1-1.5 hp gain. I am sure that other memebers have different views on this, and will pipe in (pun intended).
On the other hand, if I were wanting to put some money into the bike, I would focus on other issues that would give me a little more peace of mind. Such as, The "Doo", or at least a torsion sping. May-be progressive spings for the front end, or a fork brace.
The bike is YOUR set up, on what you want to do, this is only my $.02.
