High-quality replacement exhaust by Polini with E-mark. Polini also offers the Original Series alongside their well-known tuning parts. This matte black-coated steel exhaust was designed specifically for 50cc scooters. Polini´s expertise is reflected in the high quality of this replacement exhaust. 100% made in Italy. The exhaust system corresponds to the EC Directive 97/24/EC, Chapter 9 of permissible sound level and exhaust system of two or three-wheel motor vehicles. Performance Note: If the exhaust has the E-mark (restricted), the system is suitable for the standard engine power (OEM). If the restrictor is removed, the engine power increases considerably. Thus, the General operating permit (ABE) becomes invalid. Under certain circumstances, it may be necessary to fine-tune the carburettorand/or the variator once the restrictor is removed.
