Abstract

A one-piece exhaust line (1) for motor vehicles, composed particularly of a front silencer (3) and/or of an intermediate silencer (4) and of a rear silencer (5), these being connected to one another by means of tube portions (6,7). To make it easier to replace any one of these silencers (3,4,5), one or all of the tube portions (6,7) connected to these have connection means (9), at the front (28) or at the rear (29) of which the one-piece exhaust line (1) can be severed in order to interchange by means of replacement parts the silencer or silencers (3,4,5) located at the front (28) or at the rear (29) of said connection means (9).
