Multi-cell structure for automotive catalyst support

An exhaust system is described including an exhaust manifold having different length runners, with an emission control device housing a plurality of catalyst bricks, at least one of which having a multi-cell density. In this way, uneven exhaust mixing may be addressed without modifying packaging of...
