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.
