which yamaha/YEC parts to get?

I have a bunch of yamabucks that can only be used on yamaha parts. About $200 worth. I'm looking for mods that are yamaha or YEC branded to stick on the wrx, since I've already boughten all the oil filters and oil I need for awhile. Does anyone have any suggestions? I'm having trouble finding exactly what YEC makes for our bikes..

whoops, sorry I mean GYTR, not YEC heheh, too many bikes and I'm getting my acronyms mixed up!!

magnetic drain plug, sprockets, chain, they make dress up covers for the left side of engine bout all I can think of besides the exhaust.
