I have an FMF Turbine Core 2.1 that came off my 2019 Beta 250RR Race Edition. It does come as a full setup and has a slight ding in the exhaust. Retail is close to $500 from Beta USA. I'll sell the setup for $350. Text me at 405-361-0986 for pictures or more information. It does have the "Spark Arrestor" stamp on the exhaust.
