Description
APPROVAL
Unfortunately no e-passport/approval for public road traffic.
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. Due to its very wide speed range it is very easy to tune on 50cc and tame 70cc engines.
Please note:
In order for the scooter to reach its full power and speed, it may therefore be necessary to adjust the engine to the new exhaust with different variator weights and/or clutch springs, even if it is to be used on a stock engine. Attention. Only with modification suitable for Euro4 models
