Depending on the reason you need it, you can make an adapter plate for your S bracket so a C exhaust will fit. I have an S and I bought a Roadhouse Classic 2 into 1 exhaust that was made for a C. I just made an adapter plate that moved the S bracket back about 6 inches. I made it out of 1/8 in thick by 1 inch wide steel stock I had laying around. It worked great. Here is a link to what I did. This isn't a picture of mine,but gave me the idea.looking for factory exhaust bracket from vtx 1300C, if someone had one laying around , please let me know . thanks
