Silencer, header or full system?

On a four-stroke the system is made up of a header and a silencer, on a two-stroke of an expansion chamber and a silencer. Swap only the silencer and you keep the stock header. A full system changes the entire exhaust path and therefore has more influence on how the engine behaves. Always match the exact model, engine size and year, and remember that GasGas, KTM and Husqvarna often share the same parts. Races come with sound limits, so check what your organiser allows as well. Looking for the right HGS exhaust for your dirt bike? Use the parts finder or send us a message if you're unsure.
