fabricated at home

yeah, most likely it is a home-made cut-down. i made mine too. awesome sound and a little more power, but once i put it on my bike started running a little wierd, so i bought a power commander to remap my FI, and now it is running SWEET. it takes a couple of hours to do it right, but i think it is well worth it.
