I just received a pair of Sil Moto CF mufflers from Motowheels. These are for an '05 SS1000DS and they are oval. I am having one hell of a time mounting them properly. First, the hangers supplied are round and don't conform easily to the shape of the cans. So getting a snug fit on the can (with rubber gasket as supplied) is just not happening. Second, no matter what I've tried I cannot get the brackets to align with the pillion pegs bracket so that I can fit the bracket on the inside of the pillion peg brackets. Is there a trick to this? I currently have them fitted to the outside of the pillion peg bracket and they seem secure. But, I'm sure this isn't the right way to do it.
