Yasuni Aluminium Sport Exhaust – Classic styling, refined performance

The Yasuni Sport Exhaust was purpose-engineered for the iconic Peugeot 103 SP and 103 RCX mopeds. A lightweight design, race-influenced build and a sleek aluminium silencer deliver bold character – backed by a finely balanced, road-ready performance curve.

Configured for sport-focused 50cc and 70cc engines, this exhaust system is tuned for what riders actually use most: from initial drive-off through the mid-RPM zone. The outcome is sharper throttle response, stronger acceleration and a higher supported top speed – all achieved without modifying your motor or adjusting the carburettor setup.

Rather than requiring aggressive tuning or complex configuration, the Yasuni Carbon uses optimised exhaust flow, progressive expansion volume and intelligent pressure dynamics to give your moped more drive and more top-end speed straight out of the package.
