I think everyone shifts at low rpm around town that's pretty obvious unless you want to eat someones bumper,lol..... but the Question is where are you shifting when you get on back roads and pick up the pace....If you tell me your shifting at 3 to 6k then I would have to agree with Dave that your not using your sport bike for what it's designed for......Exileration!!! ....but that's coming from someone that disregards speed limits on backroads,I mean why own a busa if your not going to stretch it's legs here and there,lol. So, If that were the case here and I'm not saying it is but you should own something that's more of a cruiser if your more of a lay back style rider,why give up comfort for sport if your not gonna sport it up a bit here and there. As far as pipes go,most are at least making the same power at 2 to 4k and then you see an increase in power over stock from 4k to redline,even being less at 2 to 4k range the weight loss of the stock pipes....35lbs....is going to help your roll on thrust,so overall any pipe will help you in the 3 to 6k range with proper tuning which was the point about people being too concerned about peak power all the time I believe moregpz..... I know what my bike runs like after installing my Akro and PC3 and having it dyno tuned and the bike has excellent throttle response from any rpm,roll on from any gear any rpm and it pulls hard and smoothly all the way through the rev range,runs better than stock from IMO. I personally want my bike to pull as smooth as it did stock but with more power everywhere with a pipe installed,I want peak power because I use it but I want total drivability when I'm driving around town,so I agree with you Moregpz with the low end power,but dont think your giving up any power loss at that low rpms with a pipe in any way you defintely are gaining.
