We are able to reduce the engine sound with our specially designed intake and exhaust silencers.

Most of the sound of an engine is produced by the air exhaust and the air intake system.
Standard exhaust systems might reduce the sound a bit, but will not always get the sound to an acceptable level.

Our ad-on silencers can reduce the sound up to 5 db according to the type off engine, engine load, position of the silencer.

Beside the reducing of the sound level the system will also bring the frequency down.
The high frequincy of the sound is transformed to a sound with a of lower frequency.
The lower the frequency, the less irritating the sound is to the human ear.

To be able to get the best result you need to install a silencer on the air intake and exhaust.
For this reason our ad-on silencer kits contain an air intake and exhaust silencer
The silencers must not only be capable in reducing the sound produced by the pulsating air in the air intake and exhaust but must not restrict the airflow.
For this reason we produce free flowing and semi free flowing silencers.
