Abstract
A turbocharger for an internal combustion engine having a close coupled catalyst assembly includes a turbine housing having a toroidal-shaped low pressure exhaust gas chamber having a plurality of vanes disposed proximate the outer circumferential wall of the low pressure exhaust gas chamber. The vanes are arranged to disrupt the rotational flow of the exhaust gases as they exit the turbine housing to provide a more even flow though the catalyst element of the close coupled catalyst assembly.
