Seaweb if those pipes are anything like the other parts I have gotten from YAMIYA you will just fine on fit and finish. Have you got them in you hands yet, what do you think? I just wish we could get baselines on performance increases offered on a stock bike (I would like to see the differences listed between several brands, especially the Yosh knock off and X-pipe). I can not wait to hear the beast, when do you think you will have everything buttoned up?
