Exhaust Manifold direct fit for Audi Q7 3.2T Catalytic Converter Front

The automobile exhaust system mainly discharges the exhaust gas discharged from the engine operation, and at the same time reduces the pollution of the exhaust gas and reduces the noise. Automotive exhaust systems are mainly used in motor vehicles  such as light vehicles, mini cars and passenger cars.

Automobile exhaust system refers to the system that collects and discharges exhaust gas, generally consisting of exhaust manifold, exhaust pipe,  catalytic converter, exhaust temperature sensor, automobile muffler and exhaust tail pipe..

The carrier part of the three-way catalytic converter is a piece of porous ceramic material, which is installed in the exhaust pipe. The carrier does not participate in the catalytic reaction, but is covered with a layer of precious metals such as platinum,
rhodium, and palladium. It can turn HC and CO in the exhaust gas into water and CO2, and at the same time decompose NOx into nitrogen and oxygen.
