Abstract

A manifold arrangement for exhaust systems of internal combustion engines, especially multi-cylinder motorcycle engines, for installation between the exhaust gas outlet pipes from the or each cylinder and at least one muffler is configured such that the exhaust gas outlet pipes of the cylinders are combined stepwise, if applicable, so as to finally form one joint pipe where behind the joint pipe a branch is provided that divides the exhaust gas flow into at least two pipes which are separated from each other, are parallel in a flow-wise manner and together having a larger cross-sectional surface than the joint pipe and behind the pipes, parallel a joining element is provided again so as to form one single collector pipe. In order to achieve an increase in the efficiency over the full speed range, while eliminating adverse resonance phenomena and providing adequate sound damping, while at the same time having the smallest possible size, the arrangement is characterized in that the collector pipe has a free flow cross-section that matches at least the surface sum of the parallel pipes and that in the continuing collector pipe a component serving as a wave impedance is installed, which component allows the exhaust gas volume flow to pass unhindered while pressure waves are forced to perform a total reflection on the component, which total reflection is as complete as possible.
