If you like the TORs then get a set from out of state, and load the Triumph tune yourself using TuneECU. That way the dealer is happy because he didn't make any money (or lose any), you're happy because you have the pipes you like and the bike is tuned correctly (according to Triumph) for them, and California will never know.
If you want, lightly scuff them with 600 wet&dry, then hand paint them with hi-temp BBQ paint (HomeDepot). The paint will dry flat black, brush marks will disappear, and so will any "Off Road" markings.
