The Factory Exhaust System for the My20 and MY21 4-Stroke
Engine. As you can see here below, we have developed one specific silencer and three different
manifolds, all equipped with the expansion chamber to optimize the performance of every engine.
You can see which manifold diameter is recommended for each engine displacement. This is just an indication: the three manifold sizes can fit all 4T engines, giving you many possible personalized
customizations and different power outputs. No matter the combination, the exhaust system is
FIM approved (112 Db limit respected).
Fits STD front pipe ”Slipon” and KIT Front pipe!
