Hat jemand einen Mass Auspuff (massmoto.it) schon mal gesehen und vielleicht auch gehört?
Hört sich eigentlich ganz gut an.
Hello Detlev,
perhaps you might be more interested in those picture attached. They’re stainless steel aisi 304 made, the weight is 2kg each and they’re homologated with removable dB eater; provided with the suitable EU certificate; even though the sound is deeper than the stock exhaust, but just on the limit edge allowed by the ece directive. In regards to the performance, we guarantee a gain of about the 5% of power and torque from the lowest rpm, with a lower engine temperature and fuel consumption.
The price of the pair is € 680.
Should there be anything else I can help you with, I stay at your service.
Kind regards
Giancarlo
