The latest
Big Evolution 70cc exhaust system to be released from
Polini exploits even more performance and power from Piaggio engines. Designed specifically for use with Big Evolution 70cc cylinder kits making for a perfect fitment with the three holed manifold stub. The limited edition features a turned manifold pipe, this creates a venturi effect improving gas scavenging which in turn increase power output right up to 14000 RPM. The expansion chamber is hand made from 17 separate pieces making for a real visually pleasing look and the stinger pipe can be disassembled allowing you to insert different sized nozzles changing the power at different engine revolutions. Last but not least the silencer is also a new design with a larger outside diameter which Polini claim has also improved power output.
