The Silent Pro Black is the right choice for anyone looking for a very discreet sports exhaust system. The name says it all: the Silent Pro Black is a very quiet exhaust system that delivers a significant boost in top speed. Thanks to its very wide RPM range, it’s very easy to tune for 50cc and mild 70cc engines.
Please note:
Aftermarket exhaust systems generally deliver more power than the original exhaust. To obtain approval, they are factory-restricted, which may result in a shift in the power band.
To ensure the scooter reaches its full power and speed, it may therefore be necessary to adapt the engine to the new exhaust system using different variator weights and/or clutch springs, even if the system is to be used in a stock engine in its restricted form.
