YASUNI Full Exhaust System Carbon Muffler

Yasuni Carbon Sport Exhaust – Retro style, modern performance

The Yasuni Carbon Sport exhaust is engineered specifically for the legendary Peugeot 103 SP and 103 RCX mopeds. It combines lightweight materials, race-inspired architecture and a sleek carbon silencer to deliver both bold visuals and a smarter, more effective power curve.

Designed to support 50cc and 70cc sport-oriented engines, this exhaust is focused on the riding range that matters most: from standstill through the mid-RPM zone. The result is a more reactive throttle, noticeably faster launches, and a higher reachable top speed — all without the need for engine modifications or carburettor upgrades.

Instead of demanding heavy tuning or complex setup, the Yasuni Carbon lets your moped unlock its potential through efficient gas flow, progressive expansion volume and optimized pressure dynamics, giving you more speed and more drive straight out of the box.
