REPLACEMENT EXHAUST/ MUFFLERS
If you find that your exhaust or muffler is rusty, noisy, rattling, or underperforming, you must call A1 as soon as possible.
Your exhaust is an essential automotive system. Even if you suspect a problem - it must be looked at and repaired immediately.
Exhausts remove hot, poisonous gases caused by combustion from your engine.
It’s crucial to maintain, as it redirects the gases away from the driver and passengers in the cabin – and also converts these gasses into more environmentally friendly emissions.
It also reduces engine noise to legal and acceptable levels, while improving performance and efficiency.
Your vehicle’s exhaust and muffler systems are critical to efficient operation of your vehicle. Any faults or unattended wear can impact the performance of your vehicle, as well as cause harm to you and your family.
If you find your exhaust is louder than normal, if your engine is misfiring, contact us immediately for a muffler and exhaust check – you may need urgent repairs.
EXHAUST SYSTEM COMPONENT REPAIR AND REPLACEMENT
The many components in your exhaust work together to ensure gasses are directed away from drivers and passengers in the cabin and that your engine performs at peak performance. However, each component has a crucial role to play in ensuring safety and continued engine operation.
EXHAUST MANIFOLD
Your exhaust manifold is located at the front of your exhaust system, fed directly from the engine. Manifolds are prone to cracking due to extreme heat stress (sometimes withstanding over 1300°C). This connects to the catalytic converter.
CATALYTIC CONVERTER
The catalytic converter is a component that converts harmful gases such as carbon monoxide, hydrocarbons, or nitrogen oxide in an engine into more environmentally friendly emissions such as carbon dioxide, water, nitrogen, and oxygen. A catalytic converter life expectancy is about 80,000km or five years.
DIESEL PARTICULATE FILTER (APPLIES ONLY TO CERTAIN DIESEL VEHICLES)
Since 2007, government mandates have ensured a diesel particulate filter are fitted on all diesel vehicles. This captures soot (known as particulate) from exhaust gases. They are superheated and “burned off” during a regeneration cycle. These cycles can either be active or passive systems – with passive systems reliant on the heat of normal exhaust flow to trigger regeneration. They do not require fuel additives and require annual service cleaning.
INTERMEDIATE ASSEMBLY
This sits in between the catalytic converter and rear muffler. It reduces engine noise as it progresses through the combustion cycle. It’s connected to the rear muffler through an intermediate pipe.
REAR MUFFLER
The rear muffler plays the most important role in reducing exhaust noise. Gases pass through the muffler at approximately 200°C and condensation in the muffler can lead to corrosion and failure. This is more prevalent in vehicles that travel shorter distances.
TAIL PIPE OR EXHAUST TIP
The tail pipe or exhaust tip ensures exhaust gases pass away from the vehicle correctly. You can customise your tail pipe according to your own taste and style.

Most exhaust components are manufactured from aluminised coated corrosion-resistant mild steel. Some components, especially rear mufflers, are now being made out of stainless steel, or have some stainless steel content.
Exhaust systems are 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 to your exhaust system.
