Not from my experience. On my '07 250, I go between an FMF TC2 for enduros where I need it, to the OEM Messico straight silencer everywhere else with no issues. Now, if your a little borderline on jetting to start with things might be different, but not much. I like that silencer, its quiet, short, very light, and tucks in tight as to not get bent in a crash or lever the subframe. I don't like the Stealth, its too big like a 4-stroke can, had one and sold it. Too bad the '12 seems to have a different bend and I'm stuck until aftermarket comes through with a more compact solution.
