Keep the stock can with it's mounting which is supposed to be more stout, and get a straight through core. Then combine that with a 'competition' map and maybe some tweaks of the injector and the airbox. You should get more top side.
Personally, I like it the way it is. If I were to ride in the open, sand, snow, then more up top would be desirable, but I don't, so I like it the way it is.
