I was thinking about buying a Doma silencer, but before I get one I was wondering if they make any difference in power? Better? Worse? It will be going onto an '03 250 EX/C.
Tom, I put a Doma pipe on my 300 and like it a bunch! I went with the FMF Turbinecore Q for the silencer -- sparky, quiet (!) and lots lighter than the jumbo stock silencer. I'm real happy with the combo! IMO, I don't really think you get much in performance gains from a silencer on an enduro bike, so I went with the FMF for the reasons stated above.
