DOMA Silencer for KTM EXC 200, MXC 200, SX 200 2000-2004

The DOMA 200057 exhaust silencer is designed for KTM EXC 200, MXC 200, SX 200 from 2000 to 2004. On a two-stroke, the silencer cuts the noise while letting the exhaust gases through. Its rock wool packing compacts and burns away over the hours: the noise goes up and the engine loses efficiency.
