What are the available shift knobs for my 2005 STi besides the titanium one from Subaru? I bought it and installed it and don't really like it. Anyone interested in buying the titanium shift knob from me?

does it have to be a subaru shift knob? if not, then there are a lot of manufacturer's out there. some even have vehicle specific thread design for the shift knobs. others use set screws to hold the shift knob in place. next time your visiting a parts shop, ask them to see one of their shift knobs.
