A reductant decomposition reactor for use in exhaust systems is provided that includes a middle tube portion formed with a reductant injector mount, an inlet tube, an outlet tube and a mixer. The inlet tube is formed at a first end of the middle tube portion and the outlet tube is formed at a second end of the middle tube portion and both are configured to create a sealed connection to different portions of the exhaust system. The mixer fits between the middle tube portion and the outlet tube and is configured to decompose the reductant in an exhaust stream. The injector mount comprises a tube like section that connects at a first end to the middle tube portion and at a second end to an injector port of the injector mount, and is configured to reduce recirculation flow patterns in the reactor, create a high velocity flow at an inner surface of the injector mount and thereby reduce the formation of reductant deposits.
