Abstract
The invention provides an exhaust system including a cylinder head having a plurality of exhaust ports. Integrally formed with the cylinder head are a plurality of independent and separate tubes. The tubes are cast, molded or otherwise integrally formed with the exhaust ports of the cylinder head. The cylinder head and tubes eliminate the need for an exhaust flange, welding the tubes to the exhaust flange and securing the exhaust flange to the cylinder head. As a result, the present invention has less weight and improved performance over prior art cylinder head and exhaust assemblies.
