THE Evolution muffler has been developed to achieve the maximum performance and exploit power of the Piaggio 200cc engines for Vespa PE and PX equipped with Polini cylinders.
The Expansion, with its aggressive look, is completely hand-made and has 11 cones, and the silencer, made of black anodised aluminium, has a 60mm outside diameter with the base being detachable to change the deadening material.
All these features are said to improve the general engine performance, both in acceleration and in speed.
