New Polini Evolution 3 exhaust for LC Minarelli horizontal engines

Polini Motori have a new addition to add to their exhausts range with a new EVOLUTION 3 exhaust system developed to achieve max power from liquid cooled Minarelli horizontal engines.

This exhaust has been specifically designed for use with 70cc Evolution cylinders. The features are as follows:

• Completely hand made.
• Exhaust manifold flange with three holes to couple perfectly with the new cylinder and avoid possible gas escaping and power loss.
• The manifold has been connected with a turned pipe to achieve the Venturi effect and improve the quantity of the gas scavenging consequently producing a power increase up to 14,000 rpm.
• The visual look and the exhaust's dimensions have been studied to give the maximum yield when used with the TORSEN WD.
• The silencer curve can be disassembled; it's possible to insert nozzles of different diameters to increase engine revs.
• The silencer, made of black anodised aluminum is slightly longer to contain noise and varies in the internal diameter which is larger to improve acceleration.
• The base is detachable to change the deadening material.

All these features improve the general engine performance; both in acceleration and in speed, for a fun ride at the circuits.

Yasuni Tub-350 exhaust for Yamaha XMAX

Yasuni have developed a performance pipe for the Yamaha XMAX 125 that offers greater power, more torque and is 44% lighter than the standard Yamaha XMAX exhaust. For comparison, the Yasuni Tub-350 is just over 3kg lighter than the standard pipe which weighs in at a heavyweight 7.05kg, Yasuni Tub-350: 3.90kg. Also worth noting is that this is currently the only XMAX exhaust on the market that's produced using multiple cones. Stainless steel fasteners and components have been used along with a 100% carbon cone/end cover. Noise levels have been reduced with the inclusion of a resonance chamber and labyrinth system with additional mineral fibres for greater sound retention. We're informed that the pipe sounds good while still abiding to current homologation requirements. Available some time in November, price around £250.
