Complete exhaust system YASUNI muffler

Complete YASUNI exhaust system with silencer

The Yasuni Sport exhaust system has been specially designed for the iconic mopeds Peugeot 103 SP and 103 RCX. A lightweight design, racing-influenced construction, and elegant aluminum silencer offer a bold character, supported by a finely balanced performance curve tailored for the road.

Configured for 50 cc and 70 cc sport engines, this exhaust system is optimized for what riders actually use the most: from start-up to mid-range RPM. The result: a more responsive throttle, sharper acceleration, and higher top speed, all without modifying your engine or adjusting the carburetor.

Instead of requiring aggressive preparation or complex configuration, the Yasuni uses optimized exhaust flow, progressive expansion volume, and intelligent pressure dynamics to give your moped more punch and higher top speed right out of the box.
