Abstract
A method of supporting an exhaust pipe for an engine of a motor vehicle, on a vehicle body is disclosed. Initially, the exhaust pipe is formed such that the pipe is flexible at an intermediate point thereof in the vicinity of a rear axle of the vehicle, on which a nodal point of a primary natural vibration mode of the vehicle lies. The exhaust pipe has a rear section which extends rearwards from the intermediate point. Then, the rear section of the exhaust pipe is elastically supported on the vehicle body, such that the rear section is oscillatable about the intermediate point relative to the vehicle body. With a natural frequency of the rear section of the exhaust pipe tuned to a primary natural frequency of the vehicle body, the rear section of the pipe serves as a dynamic damper for the vehicle body. Also disclosed is a support structure for supporting the exhaust pipe in the manner described above.
