The invention relates to an exhaust element (10) of a motor vehicle with an internal-combustion engine. It includes a main exhaust pipe (16) and a bypass (18) mounted in parallel with the main exhaust pipe (16). The bypass (18) includes a heat exchanger (20). Moveable means (28) for shutting off the main pipe (16) and moveable means (30) for regulating the cross section offered for the gases to pass in the bypass (18) are arranged in the exhaust element. It further includes mechanical means (32) for synchronizing the means (28) for shutting off the main pipe (16) and means (30) for regulating the cross section for the gases to pass in the bypass (18), under the control of a single actuating element.
