selling my 4 month old fmf q. all of my riding buddies are running noncompliant aftermarket pipes....or uncorked; i can't even hear my rpm's. I ordered the factory 4 today. anyone else running the factory 4 on 04 wr 450? Is this lunacy? by the way, i live in california, just put a dakar dual sport kit, registering in arizona. We'll see how much i'm harrassed.
