摘要： A muffler cutter is fitted to a tailpipe of a vehicular exhaust system, the muffler cutter includes an exhaust pipe, a plurality of through-holes formed in a side wall of the exhaust pipe, a tubular heat shield plate provided around the exhaust pipe coaxially with the exhaust pipe, and a sound-absorbing heat insulator provided between the exhaust pipe and the tubular heat shield plate. The sound-absorbing heat insulator is partially provided between the exhaust pipe and the tubular heat shield plate so as to have a curved shape. A closed space having a curved shape is formed between the exhaust pipe and the tubular heat shield plate in an area in which the sound-absorbing heat insulator is not provided. The distance between the exhaust pipe and the tubular heat shield plate in an area in which the closed space is formed is 1 to 50 mm.
