I find it real interesting that the Devil Horns have added 16 cfm to the air
flow. After that awful long lecture about how they would add nothing.
Seriously, 16 cfm isn't big, but every little bit helps.

Speaking of every little bit. I wonder how the SL55 setup would flow if
they had K&N filters (or some other higher flow filter) instead of the
stock filters. Just how much would be added by the filter swap? Enough
to compete with the NW single?

Just curious...
