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.
