Exhaust Giannelli Derbi DRD Pro

Giannelli Exhaust System

The Giannelli exhaust system has been specially developed for key areas of tuning performance. On the one hand, it can extract extremely high power from stock cylinders. On the other, it is also fully compatible with 70cc and 80cc cylinder kits.

With a Giannelli exhaust, you gain a clear advantage: excellent torque even at very low revs, smoothly extending across the entire rpm range (approx. 4,000 – 12,500 rpm).
