Patent ID: 8453792

Claim:
An exhaust system of an internal combustion engine in a motor vehicle support structure, the system comprising: an exhaust pipe which carries exhaust gas from the internal combustion engine to the environment of the support structure; an exhaust muffler with a resonance volume and a connection line connecting the resonance volume to the exhaust pipe for transmitting airborne sound, the resonance volume being formed in a resonance chamber arranged rigidly in or at the support structure, the connection line comprising a flexible line permitting relative movement between the resonance chamber and the exhaust pipe; and a connection element comprising a cooling structure, said exhaust muffler being connected to said exhaust pipe via said connection element, said cooling structure cooling at least a portion of said connection element, wherein heat transfer from said exhaust pipe to said connection line is reduced via said cooling structure, wherein the resonance chamber is formed by a hollow body of the support structure.
