The upper arm is mounted to the vehicle underbody, and the lower arm is connected to the exhaust system, wherein the orientation of the upper and lower arms is substantially vertical and the orientation of the central axis of the pig tail coil is substantially horizontal. This arrangement provides a moment at each of the upper and lower arms which act to suspended weight of the exhaust system radially with respect to the pig tail coil.
