摘要： An exhaust apparatus for internal combustion engines which can reduce exhaust noises, its weight and production cost with no need to provide a sub-muffler. The exhaust apparatus is provided with an inner pipe having the upstream open end and the downstream open end is disposed in the tail pipe, and the upstream open end of the inner pipe is protruded outwardly from the inside of the tail pipe to be extended into the resonance chamber, and thus the upstream open end is closed by the resonance chamber defined by the outer shell of the muffler, the end plate, and the partition plate.

摘要： An exhaust gas apparatus suppresses sound pressure level from increasing, and reducing its weight and production cost without need of a sub-muffler in a tail pipe and a sound deadening device having an air column resonance of a large capacity provided at the upstream opened end of the tail pipe. The exhaust gas apparatus is provided with an exhaust gas pipe, an upstream opened end connected to the sound deadening device positioned at the upstream side of an exhaust gas discharging direction, and a downstream opened end through which the exhaust gas is discharged to the atmosphere. A plate is provided at least one of the upstream opened end and the downstream opened end in opposing relationship with the exhaust gas discharging direction, and formed with an opened portion. The exhaust gas pipe is formed at its peripheral wall axially inwardly spaced apart from the plate with a through bore.
