Exhaust manifold

An exhaust manifold for a vehicle engine comprising:

• a first pipe, a second pipe, a third pipe and a fourth pipe each having a proximate portion and each being operatively configured to be coupled to a corresponding engine chamber at the proximate portion;
• a pod having a pod reinforcement integral to a plurality of angled pod flanges, each angled pod flange in the plurality of angled pod flanges being operatively configured to support and align a corresponding proximate portion of each of the first pipe, the second pipe, the third pipe and the fourth pipe to a corresponding exhaust gas flow, the proximate portion for each of the first pipe, second pipe, third pipe and fourth pipe being exterior to the vehicle engine;
• a splined collector operatively configured to receive an outlet end of each of the first pipe, the second pipe, the third pipe, and the fourth pipe at a splined collector inlet, the splined collector being downstream of the proximate portion of each of the first pipe, second pipe, third pipe and fourth pipe;
• and
• a downpipe affixed to the splined collector at a small diameter outlet portion, the downpipe having a first oxygen sensor operatively configured to communicate with a second oxygen sensor;
• wherein each angled pod flange is obliquely angled relative to the pod reinforcement.
