Apparatus and method for mixing reductant in an exhaust gas flow using virtual interception. Embodiments include an exhaust gas and reductant mixer comprising a body, a first flow device, and a reductant entry port. The body defines an exhaust gas flow path having a central portion. The first flow device swirls the exhaust gas in a circumferential direction with respect to the gas flow path. The reductant entry port introduces the reductant into the gas flow path at a location downstream from the first flow device and in an introduction direction (1) offset from the central portion, and (2) opposite the circumferential direction.
