Exhaust -TECNIGAS Silent Pro- Minarelli 50cc (vertical cylinder) - BOOSTER, BUMP50, BWS50, SLIDER50, SPY, SR50 (-1994), STUNT, ZUMA50, AMICO

The Silent Pro is the right choice for all those who are looking for a very unobtrusive sports exhaust system. With the Silent Pro the name says it all, a very quiet exhaust with a significant increase in top speed. Due to its very wide speed range it is very easy to tune to 50ccm and tame 70ccm engines.

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.
