Yasuni Exhaust "Carrera 16" (or C16) Carbon/Aramid MBK Nitro / Aerox, powerful racing exhaust by renowned Spanish manufacturer Yasuni.
Sheet metal expansion chamber complemented by a carbon/Aramid silencer.
Originally developed for Endurance racing, it has a lot of torque and power at mid rpm range. We recommend combining it with a 50cc or 70cc racing or even Hyper Racing cylinder for more torque and better acceleration.
As a racing exhaust, it is of course reserved for the race track and not street-legal.
Note: for Aprilia Area 51, the height of the manifold has to be adjusted.
