Sym exhaust selection help

(Select your scooter brand and type using the filters)

2-stroke (no difference between 25/45km, separate oil tank in the seat compartment) If your scooter type is listed under the exhaust as 2-stroke, then it is the correct one.

4-stroke (no difference between 25/45km) Until 2018, Sym had two different types of engine blocks, the GY6 and the Sym. How can I determine the engine type of my scooter? This is indicated at the bottom of the engine block or on the sticker in the helmet compartment. If your scooter has the code XS1P39QMB, it is a GY6 engine, and you need a GY6 exhaust. If the code XS1P37QMA is listed, you have a Sym engine.

If your scooter is built after 2018, it is equipped with a fuel injection exhaust. This is clearly indicated in the exhaust descriptions.
