Catalytic Converter

The catalytic converter reduces harmful emissions from engine exhaust. It uses a combination of heat and metals that act as catalysts. A catalyst is a metal (or chemical) that causes other chemicals to go through a reaction without being affected itself.

The inside of the catalytic converter consists of metals like aluminium oxide and platinum palladium which work to create a reaction between carbon monoxide and hydrocarbons to produce water vapour and carbon dioxide, which are much less harmful to the atmosphere.

The muffler works to quiet the noise of the engine and there are generally two kinds of mufflers. One uses baffled chambers to reduce noise, in which the sound waves bounce off the baffles and expend their energy inside the muffler, losing force and volume. The other type forces the exhaust straight through a perforated pipe that contains metal, fibreglass, or some other kind of sound-absorbing material.

This muffler is designed to reduce back pressure (exhaust going back up the pipes) and consequently makes a little more noise.

Common Signs of Wear:

  • Exhaust manifolds and gaskets: cracks or small holes could cause exhaust leaks, affecting both safety and performance
  • Oxygen sensors: cracks, damaged wires, or blocked intakes could cause incorrect fuel/air mixture adjustments and poor fuel economy
  • Catalytic converters: overheating, dents, clogs, or corrosion could cause air pollution, excessive noise and rough idle
  • Resonators and mufflers: excessive rust or holes could cause air pollution, excessive noise and a rough idle
  • Pipes, hangers, clamps, and brackets: excessive rust or broken bolts could cause parts to hang dangerously low, resulting in a hazard for the people driving behind you

Upgrading your car or auto exhaust system is a great way to build horsepower, free up trapped torque, and improve anemic-sounding factory systems. The larger pipes, low-restriction mufflers, and tuned resonators of a well-designed performance exhaust system can make a world of difference on your vehicle.
