I think Vito's had developed it's own weird market niche that cater's to the individual who just bought a hot new bike, has some mechanical knowledge, and wants to start midifying their bike without knowing too much about the particular bike.
If I find someone who has a set of these things, I will make sure to post some pictures up of them. I would be willing to bet that the exhaust ports are ok, but I would also venture a bet that the intake side of port setup are not that they shoulf be (if they were, you would probabl see it on the outside of the castings).
IMO for hinest people worried about stock appearance, you can hide a set of cubs pretty well. If I get ahold of a new bike one of these days, I think it would be fun to see how much you could get out of a stock appearing bike (including remade expansion chambers). I think someone down in SoCal already did something like that, but I seem to g=have lost the pictures of it. :geek:
