French manufacturer Doppler has come out with a new treat! They are the only tuning specialists who produce a real sport exhaust system for the Peugot Speedfight 100. Doppler characteristics can be compared to Technigas Next "R". Like most of the tuning parts from our French neighbors, the craftmanship and materials used in construction are on the highest niveau. The Speedfight sport exhaust from Doppler purrs like a kitten. Convincing is the right word for solid performance from middle to upper rpms, providing continual stutter free power.
