Abstract
The present invention is an exhaust system having a parallelogram-shaped cross section. The exhaust system includes a header flange for connection to one or more cylinder exhaust ports. The header flange is coupled to one or more conduits. The conduits merge into a collector, which may or may not include a muffler.
Claims18
An exhaust system for an internal combustion engine, the exhaust system comprising:
- an exhaust header flange for coupling to an engine;
- a conduit having a parallelogram-shaped lateral cross-section, along an entire length of the conduit, wherein the conduit is coupled to the header flange;
- and
- a collector having a parallelogram-shaped lateral cross-section, along an entire length of the collector, wherein the collector is coupled to the conduit.

2 more elements
A method of controlling exhaust gas flow, the method comprising the steps of:
- conducting exhaust gas from an engine through an exhaust system;
- and
- preventing the exhaust gas from moving in a spiraling motion through the exhaust system, the preventing the exhaust gas from moving in a spiraling motion further comprising conducting the exhaust gas through a, flow path with a parallelogram-shaped lateral cross-section along an entire length of the flow path, wherein the flow path includes a collector.
An exhaust system for an internal combustion engine, the exhaust system comprising:
- (a) an exhaust header flange for coupling to an engine;
- (b) at least four conduits coupled to the header flange, each of the at least four conduits having an entire length with a square cross section;
- (c) at least two first “Y” connectors having an entire length with a square cross section;
- (d) at least one second “Y” connector coupled to the at least two first “Y” connectors, the at least one second “Y” connector having an entire length with a square cross section;
- and
- (e) a collector coupled to the at least one second “Y” connector, the collector having an entire length with a square cross section.
