DOMA Silencer for GAS GAS EC 250, HUSQVARNA TE 250 and KTM EXC 250 2024-2025

The DOMA 200710 exhaust silencer is designed for KTM EXC 250, HUSQVARNA TE 250 and GAS GAS EC 250 from 2024 to 2025. 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.
