Abstract

An exhaust system comprises an exhaust driven turbocharger having an outlet and a flanged portion that extends about the outlet, an exhaust treatment device comprising a canister having an inlet cone that includes an integral inlet flange defining an the inlet opening configured to define a seal with the flanged portion that extends about the outlet of the turbocharger and a substrate disposed within the canister through which the exhaust gas flows. An exhaust gas passage, fluidly couples the turbocharger and the exhaust treatment device and allows for the passage of exhaust gas therebetween and a flow modifier comprising a radially inwardly extending wall portion extends from an inner wall of the exhaust gas passage and directs the exhaust gas away from an outer radius of the exhaust gas passage to evenly distribute the exhaust gas across the an inlet face of the substrate.
