DOMA Silencer ref. 200593 for KTM SX 65 2009-2015

The DOMA 200593 exhaust silencer is designed for KTM SX 65 from 2009 to 2015. 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.
