Abstract
An exhaust manifold includes at least two flanges. The exhaust manifold further includes a first tube extending at a first constant angle from a first flange of the at least two flanges. The exhaust manifold also includes a second tube extending at a second constant angle from a second flange of the at least two flanges. The first tube and the second tube join at a collector, where the first tube and the second tube form an acute angle between the first tube and the second tube at the collector.
Claims20
An exhaust manifold comprising:
- at least two flanges;
- a first tube extending at a first constant angle from a first flange of the at least two flanges;
- a second tube extending at a second constant angle from a second flange of the at least two flanges;
- and
- the first tube and the second tube joining at a collector, wherein the first tube and the second tube form an acute angle between the first tube and the second tube at the collector.
An exhaust system comprising:
- at least two flanges configured to connect to exhaust ports of an internal combustion engine;
- a first tube extending from a first flange of the at least two flanges at a first angle relative to a plane formed between the at least two flanges, the first angle is in a range from about 50° to about 80°;
- a second tube extending from a second flange of the at least two flanges at a second angle, the second angle is in a range from about 50° to about 80°;
- a collector operatively coupled to a tuned pipe;
- and
- the first tube and the second tube joining at the collector.
A method of forming an exhaust manifold comprising:
- coupling a first tube to a first flange, the first tube extending from the first flange at a first constant angle in an XY plane;
- coupling a second tube to a second flange, the second tube extending from the second flange at a second constant angle in the XY plane, the second angle being equal and opposite to the first angle;
- and
- joining the first tube and the second tube at a collector.
