Abstract
A vehicle exhaust system is provided to improve a uniformity index (UI) of exhaust gas discharged through an exhaust manifold. The system includes an exhaust manifold for collecting and transferring exhaust gas discharged from each cylinder of an engine and a catalytic purifier connected to an outlet of the exhaust manifold to reduce harmful substances in the exhaust gas flowing from the exhaust manifold. A mesh member is disposed between the exhaust manifold and the catalytic purifier to allow the exhaust gas to pass therethrough. The mesh member includes partition walls arranged to intersect longitudinally and transversely on an inner passage cross-section through which the exhaust gas passes. The partition walls cause flow resistance while colliding with the exhaust gas to induce the exhaust gas to uniformly flow into a catalyst of the catalytic purifier.
