FMF Factory 4.1 RCT silencer

This is a genuine KTM PowerParts item supplied by the motorcycle manufacturer, not an aftermarket replacement. Silencer housing made of high-grade aluminum with a carbon silencer cap. Mounting is also possible with the original header. It provides significantly more torque, substantial weight saving and a noticeable performance enhancement. Combined with an FMF Megabomb header, even further increase in rideability and power output can be achieved.
