he doesnt have a mugen bumper, hes talking about mugen lip...bibipoo is right....
btw have you thought about how low your bumper would actually hang with that added on? not to mention the extra weight your mugen bumper would be supporting?
the mugen bumper itself is low enough that you could hit scatch some speedbumps even if your car is not lowered
if you want that splitter effect on your mugen bumper, go take a look at APR, i think they make splitters that you could add on to anything~
