Abstract
An exhaust manifold for a vehicle engine may include a plurality of pipes, a pod, a splined collector and a downpipe. Each pipe in the plurality of pipes are operatively configured to be coupled to a corresponding engine chamber at a proximate portion. The pod is operatively configured to align a flow of exhaust gas emerging from each of the corresponding engine chambers to the associated pipe in the plurality of pipes. The splined collector receives the outlet ends of the pipes at a splined collector inlet. The downpipe may be affixed to the splined collector at a small diameter outlet portion. The downpipe includes a first oxygen sensor operatively configured to communicate with a second oxygen sensor disposed in a downstream catalytic converter and an ECM in order to regulate air and fuel for the vehicle engine.
