From Italian exhaust specialist Arrow, these slip-ons for the Panigale 899 and 1199 are based on their popular Works and GP2 silencers, with new design features and exhaust layout, and a good weight reduction for improved performance. The exhaust gases pass through the left silencer to be redirected to the right-hand one with a C-shaped link pipe, therefore only the right-hand silencer has an exit pipe. Arrow says this was the key to reduce the weight and dimensions; the 899 scored 134 PS at the rear wheel in racing version (an increase of 5 PS over OE exhaust), with the 1199 reaching 174 PS - an improvement of 6 PS over the OE system. Available as homologated Works silencers with carbon end cap or GP2 silencers in titanium for the original collectors, or as a GP2 "Dark" silencer for the original collector in steel.
