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 aluminium cylinders such as Athena Sporting and Stage6 Sport pro, but also very good with 70cc cast-iron sport cylinder kit. This exhaust is equipped with a classy Aluminium silencer, but also available with the following silencer : Aluminium Black, Carbon and Carbon Kevlar. You just have to choose the silencer you want in the dropdown menu. Attention! We worked with Yasuni to made special exhaust production with no restriction inside the silencer. This exhaust only have restriction inside the exhaust flange that can be easily removed with dremel. By removing this restriction you release the full power of the exhaust which translates to better performance.
