i have a 2017 KTM 350 EXC-F that I purchased this pipe for. I used it one season (appox 50 hrs) and decide to remove it. The guys I was riding with told me it was too loud. It did increase the performance a bit but I also liked the quietness of the stock pipe. Look at the chart to see other application. Located in Mackay, Idaho. I can deliver It to the Idaho Falls area the next time we’re in town or on my way to Moab when I go there. Text is best
