  • Patent number: 12006854
    Abstract: A vehicle exhaust system includes a tubular component defining a primary exhaust gas flow path with a primary exhaust gas outlet. At least one opening is defined by the tubular component and extends through an inner surface and an outer surface of the tubular component. A plate is disposed on the outer surface of tubular component and covers the at least one opening.
