Yasuni "Scooter R" Zuma Minarelli Exhaust Kevlar

The Yasuni Scooter “R” is the evolution of the "Z," with more volume and a wider cone, making it the ideal complement for 70cc Sport/MidRace cylinders. It works very well with 50 or 70cc cylinders, but its true efficiency becomes apparent with 70cc Sports cylinders. For superb performance, we recommend modifying the variator application. Comes equipped with a good-quality Aluminum, Carbon or Carbon/Kevlar Muffler.  

Scooter R has e-pass /  noise restrictor plates welded in the muffler and header inlet.   The piping is also built around the stock center stand unlike the Carrera Racing 16 and 21.
