Exhaust Manifold Converter


The exhaust manifold converter is a catalytic converter connected directly to the exhaust manifold. Use of this type of exhaust manifold converter has been increasing in recent years compared to the conventional under-the-floor catalytic converters. The catalytic converter is an exhaust gas purification device that transforms toxic components of the exhaust gas into harmless substances through catalysis and removes them.

Exhaust manifold

The exhaust manifold collects exhaust gas from the cylinders in a multiple-cylinder engine. Generally, the exhaust manifold is incorporated into the engine, so it is sometimes not included in the exhaust system. However, the exhaust manifold greatly affects the engine output and the sound output of the exhaust system, so it should not be omitted from the exhaust system.


Manifold Converter

The manifold converter is an exhaust gas purification device that transforms toxic components in the exhaust gas, such as HC, CO and NOx, into harmless substances through catalysis and removes them. For cars whose engines have relatively small displacements, the converter is connected directly to the exhaust manifold, instead of being installed in the conventional under-the-floor position. A pre-converter or a sub-converter may be installed in front of the converter.
