I live in Mass, and the state cops here are jerks (just dont try telling that to their face, I know from experience that they dont like it too much ;) and they like to nail people for having 'altered exausts.' I know the TRD muffler is an actual toyota part so it technically isnt aftermarket, but if I get pulled over and the cop hasnt had his donut and his blood sugar is low, it might not be enough to say that. I am wondering if there is anything I could show the cops that would prove it is noise and emission legal. anyone have any experience with this?
