References of silencers to be used by motor range and impact on power

Extremely compact, these plastic silencers reduce the exhaust noise level with a minimum impact on the motor’s dimensions (or even almost zero in the case of the mini silencer). They also provide protection against any intrusion of foreign bodies into the motor via the exhaust port.
Beware, however, of the maximum possible flow rate, beyond which motor performance will be impacted (torque and speed).

Extremely compact, these metal silencers reduce the exhaust noise level with a minimum impact on the motor’s dimensions (or even almost zero in the case of the mini silencer). They also provide protection against any intrusion of foreign bodies into the motor via the exhaust port.

The unsealable exhaust silencers are extremely robust, impact resistant and made of stainless metals. They can be used in harsh conditions and environments.


“High flow silencers offer very little pressure drop and allow a very large reduction in exhaust noise. The high flow silencer is surely one of the best in terms of “Noise reduction / Flow loss” ratio.
Noise reduction up to 85%
Restitution of the inlet flow at 94%.
Made of metal components, they are very robust and offer good resistance to corrosion thanks to galvanised steel and aluminium components.
The hexagonal base allows for easy assembly.
The very large surface area of the filter element allows oil mist and other contaminants to be collected.”


The exhaust silencer reduces noise and the release of solid particles and oil droplets into the atmosphere.
It must be assembled in a vertical position (maximum 15° inclination).
Pressure losses due to clogging of the cartridge must not exceed 0.5 bar. If this is the case, change the cartridge.
Condensate is automatically drained when it exceeds a certain level. However, the draining can be done manually by turning the draining screw a quarter turn.
