Abstract

A method of manufacturing exhaust pipes with a built-in silencer, particularly for motor vehicles, comprising the stage in which: a metal strip is helically bent to a tubular shape, said metal strip is outlined to obtain a ridge and closed by helical bending in tubular form by a solid rebar seam whereby a perimeter helical seam pipe is produced by reducing the diameter of the helical seam pipe progressively in the exhaust pipe and the outer pipe of the muffler in order to obtain a continuous connection part between the outer muffler tube and the exhaust pipe.
