The Sito Plus sport exhaust system in original optics definitely belongs to the most inconspicuous sport exhaust systems at all. With the Sito Plus you can certainly not expect performance like with a real race exhaust, but the results that can be achieved with it are still remarkable. In terms of price it is usually a very interesting alternative to an original exhaust. On original cylinders or 50cc DR it is certainly a very good, inexpensive and unobtrusive choice.
The exhaust is generally throttled by means of a cone ring in the manifold, as usual with Sito and LeoVince, so the exhaust can be offered for many models with E-marking.

Please note:
Retrofit systems usually always have more power than the original exhaust. In order to obtain an approval, they are throttled at the factory, which can result in a shift of the power band.
In order for the scooter to reach its full power and speed, it may therefore be necessary to adapt the engine to the new exhaust with other variator weights and/or clutch springs, even if it is to be used throttled on a production engine.
