When I Installed my FI 14'' CB. I added 3 washers between one of my hangers and the body. Using it as a spacer so the muffler would sit lower in the cutout. My tips were not even and it bugged TF outta me!!! I wouldn't pull them futher out because Kevin @ FI has told me horror stories of them eventually coming apart :0 Told me only a half inch outta the slip fit at most! They are only adjustable side to side. (Left to Right) Mine are 3/4 of an inch from the diffuser. Haven't Melted yet!
