The S07B engine installed in the N-ONE (JG3) has a performance that can not be thought of as a K-CAR even if it is normal even though it is 660cc. We have been developing a muffler with the goal of optimizing the exhaust system that can handle high output by ECU tune such as boost up from normal. The pipe diameter and layout adopt a different diameter megaphone shape of 50? ? 60? ? 65? based on the results of the N1 muffler kit for S660, and the intermediate silencer has a straight structure instead of a partition type, sacrificing torque in the low speed range. The output has been improved in the mid-high speed range and a high-quality N1 sound has been achieved. Remarks & special notes Common to 6MT and CVT vehicles. Obtained JQR certification. Conforms to safety standards. Proximity exhaust noise: 87db Acceleration running noise: 81db Material Pipe: SUS436, Silencer: SUS304
