Abstract: The present disclosure relates to a vehicle exhaust assembly (1) for an internal combustion engine. The vehicle exhaust assembly (1) comprises an exhaust system (3) and an exhaust mounting assembly (4) for mounting the exhaust system (3) to a vehicle (2). The exhaust system (3) comprises an inlet section (5) for connection to the internal combustion engine; an intermediate section (6) connected to the inlet section (5); an outlet section (7) for exhausting gases from the internal combustion engine; and one or more exhaust decoupler (8) for decoupling the intermediate section (6) from the inlet section (5). The exhaust mounting assembly (4) comprises one or more first isolator device (20-1, 20-2) for resiliently constraining movement of the intermediate section (6) of the exhaust system (3) in a longitudinal direction; and one or more second isolator device (20-3, 20-4) for resiliently constraining movement of the outlet section (7) of the vehicle (2) exhaust in a transverse direction. The present disclosure also relates to a vehicle (2) including a vehicle exhaust assembly (1).

Abstract: Aspects of the present invention relate to an active noise system (4), a vehicle (1) with an active noise system (4), a method for controlling an active noise system (4), a computer program for controlling an active noise system (4) and an active noise controller (40). The wading detection system (3) includes sensors (30, 31, 32, 33) for detecting a wading depth and a wading detection controller (34). The active noise system (4) includes speakers (41, 42) for modifying the exhaust noise emitted from the vehicle (1). The wading detection controller (34) is operable to detect or anticipate a predetermined wading depth (W1, W2) at which the speakers (41, 42) will come into contact with the water. The active noise controller (40) is configured to deactivate the speakers (41, when the predetermined wading depth (W1, W2) is detected or anticipated by the wading detection controller (34).
