The low-positioned slip-on with link pipe can only be mounted if the pillion passenger frame is removed. An additional aluminium muffler holder from BMW’s accessories range (BMW product code 77 11 8 564 071) must be mounted, and covers for the main frame’s threaded fasteners (BMW product code 77 25 8 536 857) are also recommended to hide the unattractive screw connections on the main frame.
