Arrow Extreme 'e' approved powerpipe with titanium silencer. Aggressiveness, lightness, silence are the main features of this new series of homologated exhaust systems for 50cc scooters. The Extreme exhaust is made from a thin iron sheet oxyacetylene welded and is painted with heat-resistant varnish. The silencer is composed of stainless steel end caps and internal core, while the sleeve is in titanium. These features allow the reduction of the weight of this exhaust of the 40-50%, in comparison with the original equipment. In compliance with the European directives, the noise level of the Extreme exhaust is the same as that of the stock exhaust, and the improvement of the performance it gives is within the limits imposed. We advise that the variator rolls be changed in order to achieve a better performance in acceleration. It comes with a lacquered finish but must be painted with high temperature paint once the lacquer has burnt off to avoid corrosion.
