Disclosed is a vehicle exhaust assembly comprising an exhaust system 3 and an exhaust mounting assembly 4, the exhaust system comprising an inlet section 5, an intermediate section 6 connected to the inlet section, an outlet section 7 for exhausting gases from the internal combustion engine, and one or more exhaust decoupler 8 for decoupling the intermediate section from the inlet section, and the exhaust mounting assembly comprising one or more first isolator device 20-1, 20-2 for resiliently constraining movement of the intermediate section in a longitudinal direction, and one or more second isolator device 20-3, 20-4 for resiliently constraining movement of the outlet section in a transverse direction. The one or more exhaust decoupler may comprise a flexible conduit, a convoluted tube or a metal braided conduit. Also claimed is a vehicle comprising a vehicle exhaust assembly. The arrangement reduces mechanical loading on the exhaust system in use which allows a lower grade of material to be used, thereby reducing mass.
