The Freak (from newspeedmaster.com) is one (probably the most popular) method of utilizing the pod filters. But there's the "Ghetto Freak" (basically hacking up the stock air box to make room for the filters) and a few battery-relocation methods (the hacked stock battery box bracket utilized by Brokenfixed and others, and I believe Boogieman has a bracket for sale as well). In late '02 I designed and built my own battery relocation box.
The only two issues with just simply removing the airbox and calling it good is (1) the gaping hole in the right side of the bike since the airbox is what the side cover mounts to, and (2) keeping mud and road grime from being flung onto everything by the rear tire. Otherwise you don't really "need" anything more than the filters.
