My Catalytic converter went missing... a frustrating experience but I'm positive there is a lost cat poster joke in there somewhere. Anyway, the OEM cat is like $700-$1400 depending on which dealer you ask but an aftermarket unit is $200. I thought this was great news, a high flow cat for cheaper than OEM! Then I realized that takes me out of street class, I think I should be and into Street Touring, maybe STR? So long story short, how do I get myself moved now that I've already registered?
