thats what i did with mine, however i needed to buy another piece. I dont think thats the "up" position though, I think thats literally putting the filter pointing up towards the fenderOnceBitten said:I've always found descriptions of the "UP" position to be horribly misleading. What they mean by the "UP" position, is to completely remove the in-fender piping and place the filter directly behind the fender plate without using any of the elbows or piping beyond that point. I spent hours trying to figure this one out for myself. Good luck.
