1. A three-way catalyst (TWC) assembly configured to mount along an exhaust flow path of a reciprocating combustion engine, comprising:
a housing comprising an inlet, an outlet, a wall, and a port disposed along the wall between the inlet and the outlet, and a flow path between the inlet and the outlet; one or more catalyst elements disposed in the housing along the flow path; and an emissions sampling probe integrated within the housing along the flow path, wherein the emissions sampling probe comprises a tube disposed within the port, a first portion of the tube extends through the wall into the flow path within the housing, and a second portion of the tube extends through the wall outside of the housing.
