FMF Turbinecore 2 Spark Arrestor. Fits: KTM 200SX 2003-2010 & 200EXC/MXC/XC 2004-2010. Most pictures shown are provided by the product's manufacturer and may be generic to cover many models of vehicles.
I bought a bike with the FMF fatty and power core silencer already on it. I needed a silencer that had a spark arrestor for trail riding so this was a perfect fit.
