What kind of bags will you be using? If there is no worry of them sagging down, mount the bags just high enough to clear the pipes by about 1-1 1/2 inches. I have used a piece of aluminum on the very underside of the bag and put them very close ( 1/2 inch) with no prob. Remember also...if you switch pipes later, the new type of pipes will probably be a different height. Best idea for position? mount your brackets ON THE FENDER RAILS, Put something the inch or so you want the bags higher than the pipes down the length of the pipes( a 1 inch thick piece of wood on the cold pipes) and put the bags on them. Put something under one end to bevel them to what looks good to you. Eyball what you think is right from a distance, decide if thats how you want them. If yes, outline the easybracket top corner position, transfer this to the other bag, and mount 'em. Hope this helps.
