An exhaust system comprises a conical shell having an indentation traversing the exhaust passage in a coiled path so as to impart mixing on an engine exhaust gas flowing through an inner passage defined by the conical shell. The indentation may be formed into the conical shell via a stamping process.


1. An exhaust passage for receiving engine exhaust gas, the exhaust passage having a mixing region comprising a first portion upstream of a second portion, the second portion comprising an exterior wall having a continuous helical trough depressed onto the exterior wall and wrapping around the second portion, the trough formed as an inwardly-protruding indentation traversing at least once around the exhaust passage in a coiled path angled with respect to a cross-section of the exhaust passage, the exterior wall defining an interior passage configured to ...
