Underdrive Pulleys?

I saw that underdrive pulleys are available for the M3 and i know thats a pretty common mod for other cars that Ive had before, but ive never seen anyone talking about it for our car. Im not really sure how our whole accessory system is set up, so it might not be possible but can anyone tell me more about this for the n52?
