GIANNELLI SCOOTER EXHAUST

• This is a sophisticated exhaust system for 50 cc standard engines and 70 cc sport cylinders.
• Giannelli Extra V2 Sport Exhaust - Big on performance, small on price.
• The expansion chamber with internal mechanical silencer is MIG welded and the aluminium rear silencer is finished with a titanium look.
• The resonator comes with a clear lacquer coating. But it is advisable to apply additional coats of heat-resistant clear lacquer for corrosion protection.
• The best news is that the Giannelli Extra V2 exhaust is "E"-marked and street-legal (see model list below)

Note: As with all performance changes, the variator must be adjusted because the Giannelli Extra V2 sport exhaust alters the torque, and the optimal shift point is moved. The main jet should be approx. 10% larger than the original.
