you wont get that much, depending on the pipe, you'll beef up the lower and midrange by about 2-3 hp, and top end depending on the pipe, 3-4hp, full systems will get you a extra 2-3hp over the slip-ons if your lucky.... again, depends on the pipe, but it wont make you any faster....
THe slipon pipes alone does not really increase HP all that much, lets just say you will probably not notice the difference other than the sound. But i heard a story at one of the Dyno days at RMS, and there was two exact R1's one with Yoshimura full system, and one with Hindle full system,. The yoshimura system made one more peak HP over stock, thats right, one more HP. the Hindle system made 18hp more than stock!!! the yosh guy was pretty pissed. ANyways, it all comes down to the proper jet kit, or fuel injection kit. For exmaple, Powercommander, or the Yosh EMS system, they are both made by dynojet thou. An exhaust system plus a PCII can be a very good combination. But if you just have a exhaust system with out out a PC, then it is not used for more of its potential. just me $.02
Generally a slip on will give you a couple of ponies up top and *might* smooth the torque delivery if your stock setup has some EPA holes. But for the most part slipons are put on for the sound and full systems are put on, along with jetting changes, for sound AND power.
On a 600 the top end will go up maybe 5 HP with the full system and carb jetting. Midrange gains depend on the bike and how bad the stock system has holes in the performance. The best thing would be to do some web searches for people that have posted Dyno charts of the before and after for your model bike.
With the right jetting and full system combination you can get anywhere from 5 hp up. Also aftermarket systems weigh a shit load less than a stock one. Any weight loss and you will go faster. Go on a diet and youll ride faster.
