Abstract
A method of forming an acoustic volume in a vehicle component includes providing a vehicle frame member that includes a hollow cavity, forming an internal shell that is completely sealed and which includes at least one connection point, and locating the internal shell within the hollow cavity. At least one exhaust system component is connected to the internal shell at the connection point to provide at least one acoustic volume.

A method of forming an acoustic volume in a vehicle component comprising:
- providing a vehicle frame member that includes a hollow cavity;
- forming an internal shell that is completely sealed and which includes at least one connection point;
- locating the internal shell within the hollow cavity;
- and
- connecting at least one exhaust system component to the internal shell at the connection point to provide at least one acoustic volume.
A vehicle exhaust system comprising:
- a first component that receives exhaust gas output from an engine;
- a first exhaust assembly fluidly coupled to the first component to define a hot end of a vehicle exhaust system;
- a second exhaust assembly fluidly coupled to the first exhaust assembly to define a cold end of the vehicle exhaust system, wherein an exhaust gas temperature at the hot end is higher than at the cold end;
- a frame member that includes a hollow cavity;
- an internal shell that is completely sealed and includes at least one connection point, wherein the internal shell is received within the hollow cavity to provide an internal acoustic volume;
- and
- a neck that connects to the connection point of the internal shell such that the internal acoustic volume is in parallel to the hot end of the vehicle exhaust system.
A method of forming an acoustic volume in a vehicle component comprising:
- providing a vehicle frame member comprised of a composite material that includes a hollow cavity;
- and
- connecting at least one exhaust system component to the hollow cavity to provide at least one acoustic volume that is in parallel to the exhaust system component.
