The K&N filter, without a doubt, makes the bike feel more responsive, and tends to make the bike sound and feel better to ride.
Top end, there's probably not really much of a boost at all, as i've had my bike Dyno'd a few times,and tried re-jetting it (which it didn't like), and it still chucked out similar speeds, but for general riding the K&N to me is a definite improvement.
My bike was in very good hands at PDQ, but the general consensus was "It is what it is."
As for conical filters, i believe people have tried them, but they're not easy to set up, and to me are unnecessary, as they're more for looks than performance.
Basically, if you want a quicker bike, buy a quicker bike. :b
