Selling my titanium Akrapovic slip on exhaust. These will bolt right up into the stock header of the 350f or xcf and 450f or xcf 22.5-24 I’m not sure about the 250f so please do your own research on what else it fits. I had it on my 2023 KTM 450 sxf for about 3 hours. Some light scratches to be expected but it’s really in good shape and sounds great!
