When we wanted to increase the performance of the Husqvarna Vitpilen 701, we immediately wanted to remove the catalyst, but we realized that it served as a bracket for the belly panels. So we found ourselves faced with a dilemma, design or performance? We have chosen both and developed a bracket to remove the catalyst while keeping the covers and keeping the lines of the bike. The parts are laser cut aluminum. Easy to assemble, you will find our tutorials in pdf and video.
