Arrow 72634PRI Pro-Race Slip-on Exhaust, Nichrome For BMW R NineT Urban GS ’17-’20

Arrow’s 72634PRI Pro-Race Slip-on Exhaust, Nichrome with Steel End Cap is made specifically for BMW R NineT Urban GS (2017-2020).

Pro-Race silencers design comes from the first prototypes made for MotoGP. Pro-Race silencers are built putting together a conical-shaped part (the main body of the silencer) with a cylindrical ending section (ø98mm) and these are available in titanium or nichrome (a stainless steel alloy).

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 and the application on bigger or demanding engines.

Pro-Race silencers are available both in a street legal and racing version.
