A muffler shell is formed from a sheet metal blank. The shell comprises a tubular body section which is rolled into a tube so that a first edge of the blank can be welded to an intermediate seam line across the blank. An aerodynamic shield extension projects integrally from the tubular body section between the intermediate seam line and a second edge of the blank to cover a gap between the muffler and adjacent structures when installed on a vehicle.
