The Giannelli Ipersport for the KTM Duke 125 is similar to the Arrow models and is simply mounted instead of the original exhaust system. The use of high quality titanium changes the sound for the better and in the middle speed range the exhaust system can also increase the performance a bit. When the dB killer is removed, the sound becomes extremely, but sporty loud. However, this means that the exhaust system loses its EC type approval. We also deliver the holding clamp, the middle pipe and the necessary mounting material for the rear silencer.
