I would like to have a pipe for my 99 R6. My conditions are that I am not a track rider, so I don't need a track system. I like the noise of a pipe but not so excessive that I can't leave for work in the morning. Also I want more power in the bottom and a little in the mid-range, again I ride on the street. Now don't get me wrong I love speed, especially out of the turns. I have been told that slip-ons are a waste of money. Yet full systems require jetting and tuning (X-tra $300). I need some advice
