Exhaust Yasuni R (Alu) (street-legal)

Details
The big brother of the Yasuni Z: thanks to a larger expansion chamber and wider downpipe diameter, the Yasuni R is the ideal complement for 70cc sport and racing cylinders such as MHR Replica, Corsa etc. The exhaust’s characteristics are similar to ForRace or Nardo. Yasuni has found a clever way to attach the rear silencer (with seal rings and spring). Silencer comes in a classy aluminium look.
(with e-mark, restricted with a reduction in headpipe and rear silencer!)
