DOMA Silencer for HUSQVARNA TC 250, KTM SX 250 and GAS GAS MC 250 2019-2023

The DOMA 200684 exhaust silencer is designed for KTM SX 250, HUSQVARNA TC 250 and GAS GAS MC 250 from 2019 to 2023. 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.
