2g bumper license plate removal

I'v been woundering how people get the bigger gap in their 2g front bumper. I will be pruchasing a fmic in the near future and i will need the space. If you have performed this on your car or anyone elses please list the way you went about it. Do I take a dremel tool to it or what? And have you had any trouble with the law about not having a front license plate.
