YASUNI Scooter Aluminium R Exhaust

The "R" is the evolition of the "Z" with more volume and a wider cone, making it the ideal complement for 70cc Sport/Race cylinders. It works well with 50cc and 70cc cylinders but its true efficiency becomes apparent with the 70cc Sport cylinders. For superb performance we recommend modifying the variator application.
