Racing exhaust system from SIMONINI RACING with carbon Silencer - high RPM resonance exhaust for PIAGGIO 125-180 cc Engines.

The exhaust system is a successor (with minor modifications) to the rare HESTER system, which is no longer in production, and is aimed at performance-oriented setups with a focus on high revs.

The Italian tuning company SIMONINI RACING stands for uncompromising power delivery - looks are clearly of secondary importance here. The resonance exhaust kicks in very late: From around 9,000 rpm, the Exhaust starts to pick up significantly and maintains the power output until around 11,000 rpm. This makes the system particularly suitable for racing and high-rev setups in which the Engine is consistently driven in the upper rev band. Due to the high volume, the system is not recommended for road use, but delivers a very pronounced power characteristic in the upper range and is therefore an insider tip for pure performance applications. The system is supplied including mounting material.
