An exhaust system for an internal combustion engine which comprises an exhaust manifold connected to said engine, a communication pipe connected at one end to the exhaust manifold, a bellows type exhaust tube connected at one end to the other end of the communication pipe, a second communication pipe connected at one end to the other end of the exhaust tube, a muffler connected at one end to the other end of the second communication pipe and a tail pipe connected at one end to the other end of the muffler. The exhaust tube comprises a multi-layered bellows, a cylindrical wire blade, or wire mesh shield, in outwardly radial spaced relationship to the bellows, the opposed ends of the cylindrical wire mesh shield having a reduced diameter, and retainer rings securing the opposed ends of the wire mesh shield to the communication pipes.
