This exhaust system of the brand Gianelli is similar to the models of Arrow and differs from them only by the missing carbon end cap. The system is easy to install and has a positive effect on the sound of your Honda CBR. According to the manufacturer, a slight increase in performance can be expected, especially in the mid-range. The sound of the system can be changed again by removing the DB-Killer and thus increase the volume. However, we would like to point out that then the EC-registration loses its validity. The scope of delivery includes the rear silencer with mounting material, a retaining clip and the matching centre pipe.
