Sport exhaust for Vespa models with headlight on the fender (so-called lamp down models). The original look of the original exhaust was almost retained, the performance values, however, correspond to that of a modern two-stroke resonance system. Only with such an exhaust can the full potential of a tuning cylinder be explored. However, it also offers a considerable increase in performance on original engines.
Identical in construction with VSP. Widebox, SIP Road XL, Bollag etc.
