Zusammenfassung:	An engine exhaust system comprises duct pieces (20 1 , 20 2 ) and a sealing joint (30) for interconnecting their adjoining ends. The sealing joint (30) comprises a one-piece tubular body (31) including includes a first axial end portion (33 1 ), a second axial end portion (33 2 ), and a bridge portion (34) extending between them. The first end portion (33 1 ) is at least partially positioned within a female recess (23 1 ) of the first duct piece (20 1 ) and the second end portion (33 2 ) is at least partially positioned with a female recess (23 2 ) of the second duct piece (20 2 ). Depending upon the thermal expansion-contraction conditions in the exhaust system, the bridge portion (34) can extend across a gap (24) and/or it can be positioned partially within female recesses (23 1 ) and (23 2 ).
