Whether you are a performance car enthusiast, a 4x4 owner, or just want a better note from your car, we can make your vehicle perform better & sound better. Located in Nambour, servicing the greater Sunshine Coast.
Your vehicle's exhaust system has a critical role to play in the efficient operation of your vehicle, and for the safety of you and your family. Your vehicle's exhaust system functions in the following ways:
- Removes hot poisonous gases produced by your engine, keeping these gases away from your vehicle and its occupants, converting them into more environmentally friendly emissions.
- Reduces engine noise to acceptable and legal levels, and improves your engine's performance and fuel economy.
SOME THOUGHTS ON EXHAUST COMPONENTS
Most exhaust components are manufactured from aluminised coated mild steel, which resists corrosion. Some components, especially rear mufflers, are now being made out of stainless steel, or have some stainless steel content.
The exhaust system is attached underneath your vehicle by rubber hangers or mountings. These help reduce problems caused by vibration. It is important to have the condition of these hangers checked when your vehicle is being serviced to prevent damage or cracking to your exhaust system.

Many components come together to make a quality exhaust system. Each component has a different role to play. This section of our website aims to help you understand the role of exhaust system components, and the reason some fail.
EXHAUST MANIFOLD / EXTRACTORS / HEADERSThe exhaust manifold is at the front of your system, bolted on to the engine. In some cases the manifold will have been replaced by extractors or headers. Manifolds are usually made out of cast iron and are prone to cracking due to the extreme heat they have to withstand (up to 1300°C). In recent years vehicle manufacturers are fitting Manifold Catalytic Converters as an intergrated part of the exhaust system. This is in part because the cat-manifold design ensures the cat is positioned where the exhaust gasses are at their hottest as they escape the engine. The hotter gases are burnt off, this results in less emissions and a more fuel economical vehicle.
ENGINE PIPEThe engine pipe connects the manifold to the catalytic converter. Exhaust gases will have cooled down to around 1100°C by the time they pass through the engine pipe. Again, the most common reason for engine pipe failure is cracking due to excessive heat.
CATALYTIC CONVERTERAs its name implies, this component converts the harmful gases produced by an engine. Three way converters are the most common in today's vehicles. They contain a ceramic substrate (honeycomb like biscuit) which is impregnated with three precious metals (usually Platinum, Palladium and Rhodium). As the engine's harmful gases pass through the substrate, they are converted from hydrocarbons, carbon monoxide, nitrogen oxides into carbon dioxide, water, nitrogen, and oxygen. This catalytic reaction starts as operating temperatures reach 200°C, with optimum efficiency reached at 600-800°C. The life expectancy of a converter is around 80,000 kilometres or 5 years, whichever comes first.
DIESEL PARTICULATE FILTERDiesel Particulate Filters are an industry response to the ongoing tightening of exhaust emission standards for diesel vehicles. As their name suggests, they clean the particulate matter (soot) from exhaust gases by passing them through a filter that traps the particles. The DPF collects these nasty particulates as we drive along, and periodically they are superheated and burnt off in what is known as a 'regeneration' cycle. There are two DPF 'regeneration' cycles, active and passive. An active regeneration cycle injects additional fuel into the engine to create the high temperatures required for burn-off. Other DPFs have an injector that injects either diesel fuel or an additive directly into the filter during the regeneration process. DPF systems that are able to regenerate themselves using only the exhaust gas stream, without additional energy inputs, are known as passive systems. Note: Only certain diesel vehicles.
FRONT / CENTRE / INTERMEDIATE MUFFLERIn between the catalytic converter and the rear muffler is a front / centre / intermediate assembly. In some systems this component consists of a resonator positioned at the front, and a muffler at the rear. This is where the system starts to reduce the noise made by the engine as it goes through the combustion cycle. A resonator is a simple small muffler that takes the resonance out of the noise going through the system. The front / centre muffler tends to be more complicated in design, so that it continues to reduce the noise.
INTERMEDIATE PIPEAn intermediate pipe connects the front assembly to the rear muffler. This component goes over or under the rear axle dependent on the vehicle type.
REAR MUFFLERThis component gives the final note to your exhaust system. The temperature of the exhaust gas as it passes through the rear muffler is around 200°C. Condensation forms in the muffler and can cause corrosion leading to system failure. Corrosion of rear mufflers is particularly aggressive on vehicles that travel short journeys.
TAIL PIPE / EXHAUST TIPYour system is usually finished off with a tail pipe or exhaust tip. The tail pipe ensures that the exhaust gases pass away from the vehicle correctly. Exhaust tips come in many sizes and styles and purely give your system a finished off look.
While we specialise in brand new performance exhausts and 4x4 exhaust upgrades, one of our core services is exhaust repairs for all makes and models of cars, but in particular 4 wheel drive vehicles.
A damaged, old or worn out exhaust system not only sounds ugly, but your car’s performance will be reduced, likely resulting in an increase in fuel costs as well.
Not all exhaust systems need to be replaced. Sometimes a simple repair and some TLC is all it takes to get your vehicle’s exhaust back to optimum performance.

When it comes to looking after your exhaust, you don’t necessarily always need to repair or replace the entire exhaust system. Often it will just be the muffler that needs replacing on a 4x4, performance car or regular passenger vehicle.
Exactly as the name suggests, the muffler muffles the sound so your vehicle sounds good rather than rough and loud. Moisture can build up in mufflers, causing them to rust out and form holes that degrade the tone and performance.
At Burnside Motors we can match and fit a brand new muffler to your vehicle in quick time and for a great price, so talk to us about muffler replacement today.
4x4 PERFORMANCE EXHAUSTS
If you are looking for quality 4x4 exhaust systems, we are your top choice on the Sunshine Coast for performance exhaust systems, whether it be fitting a brand new system, exhaust maintenance or exhaust repair. 4x4 owner or performance car enthusiast, we can help your vehicle perform better as well as sound amazing.
A 4x4 performance exhaust is also built tough to handle Australian conditions, so you can be sure when you book in for 4x4 exhaust upgrades with us that your new system will serve you well for many years to come.
Although we specialise in exhausts for the 4x4 market, we offer a comprehensive range of performance exhaust systems for all makes and models, improving tonality, performance and, in some cases, even increasing fuel economy.
You don’t want to fit just any exhaust system to a 4x4 vehicle or performance car. A specialised system is always the best option. With a 4x4 performance exhaust system fitted to your vehicle you’ll notice the difference right away.
There are a few quality manufacturers and exhaust models to choose from to suit every vehicle, owner requirements and your budget. No matter which system you decide on, Burnside Motors are your local experts when it comes to helping customers make a decision on 4x4 exhaust upgrades, and fitting the new exhaust in a timely manner.
