As much as I love the sound and power I found it a bit loud considering some of the times I ride. I use the bike to go to work at some real early times in the morning and there are a lot of young families in my area and I really don't want to cause anyone any grief at 5AM. My muffler is a modded XB9 muffler that I had on my 12Ss. The pic attached is the one of it when I got it from Randy last fall. It has about a thouand kilometers on it now. I'm open to reasonable offers on it including trades. I get a deal through Fedex so it will come to you overnight. I am in Newfoundland Canada just to give you an idea where it's at. Asking $250 plus shipping. Email me at [email protected]
