i have one on mine, as people have said its a cheap mod and looks the part!
i attached mine with some screws and washers on the two middle bits to stop it bowing and then pop rivits on the rest of the splitter! it was not moving........................
until i bumped into a curb on friday and pulled the middle of it down
and now since its lower, i've caught it a few more times and its coming off even more. and as its pop rivited on, i can't just pull it off, gonna have to take the bumper off to reattach it i think
