The cast O2 sensor housing divorces the wastegate and turbine discharge ports with this cast and machined boss. Separating the two flows adds power and increases spool, since it reduces backpressure, as well as flow interference/turbulence when the wastegate is open. Ideally, flow is re-merged over six inches downstream, but in order for the kit's O2 housings to bolt up to the stock cat locations, the housing was cast to merge the flows earlier.
