Exhaust -SITO PLUS- Gilera Runner 50, Stalker, Piaggio NRG MC2 (-1998), NRG MC2 (1999), ZIP SP (1996-2000)

The name SITO is a synonym for high quality replica exhaust systems at fair prices. Visually they resemble the original exhaust systems. But the inner values are optimized for better performance. The systems develop more torque in the lower and middle speed range, the scooter accelerates more powerfully and reaches a higher top speed.

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 cause a shift in 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.
