This “SM-S” muffler was designed for planes that have a shoulder (high wing) configuration. This model is also perfect for a cabin-type plane (Ex: Trainer). This mid-sized SoundMaster was designed to direct the exhaust down and away, under the wing. The SM-S is rated for engine sizes .40–.65 cu. in.
