摘要： A vehicle exhaust system structure capable of easily improving output performance in comparison with a two-cylinder internal combustion engine having the same displacement and outputting an appealing and excellent exhaust sound relating to the two-cylinder internal combustion engine, in a four-cylinder internal combustion engine or a three-cylinder internal combustion engine. An exhaust pipe structure for an internal combustion engine is configured such that exhaust pipes are respectively connected to four cylinders of a four-cylinder internal combustion engine, the two exhaust pipes of the exhaust pipes are formed as long exhaust pipes having a long pipe length while the other two exhaust pipes thereof are formed as short exhaust pipes having a short pipe length, and a difference in a pipe length between the long exhaust pipes and the short exhaust pipes is set to 150 mm or more.

摘要： A silencer includes conduit with a downstream end portion configured from a tubular member which includes a conduit discharge port extending through a silencer main body and discharges exhaust gas to the outside therethrough. The tubular member includes a resonance communication hole communicating with a resonance chamber and an upstream side communication hole and a downstream side communication hole communicating with a second chamber. A barrier wall serving as a throttle portion for throttling an exhaust path at an intermediate location of the tubular member is provided in the inside of the tubular member and between the upstream side communication hole and the downstream side communication hole.
