Abstract
A vehicle exhaust system includes a tubular component defining a primary exhaust gas flow path. At least one opening defined by the tubular component extends through an inner surface and an outer surface of the tubular component. A patch covers the at least one opening. The patch includes a plate disposed on the tubular component. The plate defines at least one flow channel to receive exhaust gases from the at least one opening and impart at least one directional change to the received exhaust gases. The plate further defines at least one outlet opening adapted to receive exhaust gases from the flow channel. A secondary exhaust gas flow path is defined through the at least one opening in the tubular component, the flow channel defined by the plate, and the outlet opening defined by the plate.
