Exhaust systems

Car exhaust system services

Your car’s exhaust system has several functions: to reduce engine noise, reduce pollution, improve performance, fuel economy and direct poisonous gases away from the car and the people inside.

The exhaust system is like the “lungs” of your car - it shoots the gases that runs inside your engine out, and the way it is done can affect the performance of your car. If you have poorly running exhaust system, it will affect your fuel economy and may also fail a vehicle emissions test. So, it’s important to ensure you keep your exhaust system in great condition as replacing it can be costly.


Common exhaust system issues and warning signs

Some of the signs that there are problems with your exhaust system include:

  • Exhaust rattles or drags on the road
  • Excessive exhaust noise
  • An unusual exhaust smell

What does an exhaust do?

If you've ever heard a car engine running without an exhaust, you’ll know what a huge difference the exhaust system can make to the noise level. Inside a car exhaust, you'll find a deceptively simple set of tubes with some holes in them. They are designed to reflect the sound waves produced by the engine in such a way that they partially cancel themselves out. But exhaust systems are about more than sound reduction; they also control and reduce the emissions from the car engine using a catalytic converter. A catalytic converter is one of the most important parts of a car's emissions control system. Its job is to convert harmful pollutants into less harmful emissions before they ever leave the car's exhaust system.


Exhaust system components    

Key components of your exhaust system include the manifold, catalytic convertor, mufflers and pipes. All of these elements must be in good condition to ensure your vehicle runs and operates safely and effectively. Most exhaust systems today use bolt-on bolt-off components so repairs can now be performed safely and quickly by repairers like Kmart Tyre & Auto Service.


Exhaust system repairs

Vehicles can create dangerous gases during the combustion of fuel. It is very important to have your exhaust system repaired when leaks or potential problems are found. Those dangerous gases can be harmful if they leak into the cabin of the vehicle, so proper exiting of the exhaust emissions is to direct them out through the catalytic converter, muffler and tailpipe.

At Kmart Tyre & Auto Service we can identify problems and replace mufflers and catalytic converters, leading to reduced emissions and noise while driving. All work is backed by our industry-leading Australia-wide guarantee.
