Ok, I'm starting to think of my winter mods since winter is the only time I can't ride.  darn snow.
I'm thinking a cone filter and new exhaust.
My question is about the cone filter.  What all do I have to do?  Is it a simple slip on slip off type of thing?  I ride in all condistions minus snow and ice.  Is this bad for the filter?  If so, do I need to make some kind of cover for it?
I'm already planning on doing a spacer mod for the exhaust.
