Abstract
An exhaust component for a motor vehicle includes a wall, an internal volume, an inlet, and an outlet. The wall includes a core layer having a surface and a first layer disposed on a portion of the surface. The portion is less than 100 percent of an area of the surface. The core layer has a first composition. The first layer is a cold-sprayed layer. The core layer has a second composition different from the first composition. The first layer reduces surface-radiated noise from the exhaust component during operation of the motor vehicle. The internal volume is at least partially defined by the wall. The inlet is in fluid communication with the internal volume. The outlet is in fluid communication with the internal volume.

An exhaust component for a motor vehicle, comprising:
- a wall including a core layer having a surface and a first layer disposed on a portion of the surface, the portion being less than 100 percent of an area of the surface, the core layer having a first composition and the first layer being a cold-sprayed layer and having a second composition different from the first composition, the first layer reducing surface-radiated noise from the exhaust component during operation of the motor vehicle;
- an internal volume at least partially defined by the wall;
- an inlet in fluid communication with the internal volume;
- and
- an outlet in fluid communication with the internal volume.
An exhaust component for a motor vehicle, comprising:
- a wall including a core layer having a surface and a corrosion-resistant layer disposed on a portion of an area of the surface, the portion being less than 100 percent of the surface, the core layer comprising stainless steel and the corrosion-resistant layer comprising aluminum, chromium, manganese, iron, or combinations thereof, the corrosion-resistant layer reducing surface radiated noise from the exhaust component during operation of the motor vehicle;
- an internal volume at least partially defined by the wall;
- an inlet in fluid communication with the internal volume;
- and
- an outlet in fluid communication with the internal volume.
