Yeah it looks like I'm going to have to do some Fabbing to make slip ons work. I also noticed on the newer models the mufflers clamp vertically where mine clamps horizontally. theres also an extra bracket near the front muffler clamp on the newer models. I think I might go with aftermarket road king mufflers since there's billions of these available. Thats the thing about HD's, you can go to just about any swapmeet and find a ton of parts for them.
