The Shark Factory is first and foremost a visually and qualitatively convincing exhaust system for KTM Duke 125's. In general, Shark uses only the best materials such as real carbon and stainless steel, resulting in an unobtrusive, muffled sound. By removing the dB-Killer the sound can be improved even more, even if this means losing the EG-BE.
A catalytic converter is not included, which will improve the performance of your KTM Duke 125 by about 1hp. This also means that the EG-BE is no longer required. If you want to be on the safe side regarding the legality of the exhaust, you should definitely order the catalytic converter art.no.: 65284050. So the EG-BE of the exhaust system is waterproof!
