Yasuni Eco exhaust for vertical Minarelli scooters, including pre-2002 Yamaha Zuma CW50.

The Eco series of exhaust pipes by Yasuni feature a stock look with improved performance and unobtrusive sound. Like all European 2-stroke exhausts, there are restrictors in place that can be removed to further increase performance.

Head Pipe Bolt Hole Spacing: 48mm
Head Pipe Inner Diameter: 24mm 
Includes Mounting Hardware and Exhaust Gasket
Removal of restrictions will give more power. Restrictions are located in the manifold flange and on the silencer.
