The silencer tail in the M40 engine’s exhaust system is responsible for the final stage of exhaust gas redirection and noise reduction. Constructed from cast aluminum with machined features, this component includes a carefully designed outlet that efficiently channels exhaust gases away from the engine. Its design ensures that the exhaust gas exit is properly directed, contributing to optimal engine performance. Moreover, the silencer tail plays a vital role in further dampening exhaust noise, providing an essential finishing touch to the exhaust system’s sound attenuation. With its tight fit, the silencer tail complements the silencer body and baffle, forming a cohesive unit that effectively manages exhaust gas flow and minimizes noise emissions. As a critical part of the exhaust system, the silencer tail enhances the overall performance of the M40 engine, offering quieter operation and contributing to a more enjoyable and engaging model airplane flying experience.
