Pontiac catalytic converter is a part of the exhaust system of your Pontiac car model and is a crucial element that decides the emission control ability of your car. Ideal running engine is never possible, often the varying speed and load conditions affect the engine's efficiency which would definitely vary the exhaust emissions and as such a catalytic converter is necessary in between the exhaust manifold and the exhaust tail pipe so that partly burnt gases like carbon monoxide and oxides of nitrogen gets converted into oxygen, nitrogen and carbon dioxide that causes less harm to the environment.
But do not overlook this part if your Pontiac exhaust is noisy or if the oxygen sensor has detected more amount of oxygen in the exhaust as these are the signs of a damaged catalytic converter. Replace it immediately so that the engine's efficiency does not get affected. Purchase new less costly replacement Pontiac catalytic converter from Eastern, Walker or Bosal for durability and reliability. Less[-]
