Arrow Pro race nichrom Silencer - GreyKTM 990 990 DUKE - 2024 - 2025Ref : AW0647 / 71973PRI

The design of the Pro-Race silencer was inspired by the first prototypes produced for Moto GP.

Pro-Race silencers are constructed by assembling a tapered section (the main body of the silencer) with a Ø98mm cylindrical end section, in Nichrom (a stainless steel alloy). The mufflers are attached to the motorcycle by means of brackets welded to the main body; their cone-shaped design allows a reduction in size and weight, but as this also reduces the overall volume of the exhaust, thus limiting noise damping, some motorcycles cannot be fitted for development and noise reasons.
