What means silent?
We tested the SIMONS Silencer and compared them to other manufacturers Silencer, also measured the volume level. In every test the SIMONS Silencers were the ones with the best noise reduction. The test didn't only compare absorbing silencers but also continuous silencer without chambers. Silencers with chambers might even have a higher noise reduction but they have consequences regarding the engine performance.
Which Silencer is most suitable?
The bigger the volume of the silencer the more he can reduce noises. Use the space under your car the best possible way and choose the silencer with the highest volume. We have noticed oval Silencers reduce noises more than round ones.
End Silencer or Middle Silencer?
Because our Silencers are fully continuous, you can use them as a Pre-, Middle-, or End silencer.
