Abstract: 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 the exhaust system.

Abstract: An integrated fuel delivery and electrical connection system including an electrical bus, a fuel delivery tube and a plurality of fuel injectors is provided. The electrical bus may include openings for insertion and connection of fuel injectors, and positive and ground electrical contacts for electrical connection to respective fuel injector positive and ground contacts. The fuel delivery tube may include corresponding openings for insertion and connection of fuel injectors. A method of installing the above-identified system is also provided and includes the steps of inserting fuel injectors into openings in the electrical bus and fuel delivery tube, and thereafter connecting a single electrical harness to the electrical bus to provide electricity to the system. The electrical bus may be used in a standalone configuration, may be integrated with the fuel delivery tube, or may be packaged with fuel injectors to form an integrated package for assembly onto an automobile engine.
