Generally, the noise level and pressure drop at the exhaust pipe contradict with each other. Because low pressure drop corresponds to low damping in a conventional exhaust system, the acoustic waves from the engine cause a high level noise at the exhaust because of the resonance phenomena. In the new Muffler, the resonance phenomena is not evident by high acoustic damping because of many resistor plates provided in the pipe branched off from the exhaust pipe. The main stream of exhaust gas from the engine flows freely and almost straight, and does not reverse its course in the exhaust pipe or the muffler.
