An exhaust system for an internal combustion engine includes an exhaust pipe, and a vane mixer attached to an upstream pipe end of the exhaust pipe and including a fluid injector mount, and a fluid injection side port in the injector mount and fluidly connected to an exhaust passage in the vane mixer. The vane mixer further includes a vane extending across the exhaust passage and dividing the exhaust passage into a major flow area and a minor flow area. The minor flow area is in overlapping angular alignment, circumferentially around a longitudinal exhaust passage axis, with the fluid injection side port.
