Pro-Race silencers design come from the first prototypes made for MotoGP. Pro-Race silencers are built by putting together a conical-shaped part (the main body of the silencer) with a cylindrical ending section (ø98mm). The silencers are secured to the bike by means of mounts welded to the main body, their cone-shaped design provides a reduction of dimensions and weight, but it also reduces the overall volume of the exhaust, thus limitating noise damping capabilities. Manufactured from titanium with a replaceable dB killer for noise suppression. Requires link pipe for stock collectors.
