The disclosure provides an air/exhaust system for a vehicle, including a vented exhaust outlet with an inner tube and an outer tube having vents that draw air into a gap between the tubes to mix with exhaust from the inner tube and discharge cooled exhaust, an exhaust shield for reducing the noise emanating from the exhaust pipe, an exhaust collector with an inlet body, a neck body that causes the flow of the exhaust to converge and an expansion cone defining an expansion angle that improves distribution of exhaust flow across a catalytic converter. The catalytic converter has an inlet matrix brick formed from a foil that is thicker than a foil used to form an outlet matrix brick to improve the durability and performance. Finally, the system includes an intake duct with an interface having fingers that contact a frame member to inhibit wear of the intake duct.
An intake duct for supplying air to an intake manifold of an engine mounted to a frame assembly, the frame assembly including a frame member, the intake duct comprising:
A method for operating an intake duct, the intake duct supplying air to an intake manifold of an engine mounted to a frame assembly, the frame assembly including a frame member, the intake duct comprising a flexible body, the flexible body configured to couple an outlet of an airbox to an inlet of the intake manifold, the flexible body including a flow passageway extending through the flexible body, the intake duct comprising a first finger and a second finger connected together by a connecting segment, the first finger, the second finger and the connecting segment together defining a plurality of engagement portions, each engagement portion having a shape that substantially corresponds to a cylindrical shape of the frame member, the method comprising:
