Gianelli G4.0 exhaust

Gianelli G4.0 exhaust for Forza 125 V4 (from 2021).

Steel exhaust pipe with ceramic finish, matte black end cap and heat shield.

Designed for performance, it is 30% lighter than the original exhaust, also allowing an approximate gain of 3% in power in "homologated" configuration (with catalyst).

Road approved.
