Abstract
An exhaust tail pipe of an engine is covered at its end section with an outer cover member leaving therebetween a space communicated with ambient air. Many perforations are formed in the tail pipe end section to allow the inside of the tail pipe end section to communicate with the space. Each perforation has a diameter d (mm) within a range expressed by the following formula: ##EQU1## where A(l)=the displacement of the engine; D(mm)=the inner diameter of the exhaust tail pipe end section; and C=the kind of stroke cycle of the engine, thereby allowing a part of exhaust gas flowing through the tail pipe end section to dissipate to the space through the perforations.
