Abstract
Abstract A suspension element for the exhaust system components of an internal combustion engine incorporates interengaging resilient rings. However, these rings are not in direct contact with one another. Instead, they extend about an elastic, air-filled spherical member. This spherical member provides for the vibrations generated by the exhaust system being effectively attenuated by the suspension element before being transmitted to the floor of the motor vehicle.
