The Yasuni Scooter Z exhaust system was developed for 2-stroke scooters and impresses with precisely tuned resonance technology and high-quality workmanship. The resonance chamber supports efficient exhaust gas guidance and ensures a balanced power delivery over a wide RPM range.

Thanks to the robust construction with springs and sealing rings, the rear silencer is securely fastened and vibrations are reliably compensated. The exhaust system is suitable both as a replacement for the stock system and for vehicles with sport cylinders up to 70 ccm (depending on the model).

Depending on the version, the exhaust features integrated restrictors and EC approval. For many models, proof of homologation is provided via the permanent E-mark attached to the exhaust.
