Exhausts and Mufflers

Your car’s muffler and exhaust systems lifespan can be anywhere from 3 years to 10 years. However, this can vary depending on driving style, environmental factors and type of exhaust setup.

Exhausts and Mufflers

You might not realise just how loud a car’s exhaust system is, which is why a muffler is used to cancel out the sound. Your car’s muffler reduces the noise level and controls the engine back pressure. If your vehicle’s muffler or exhaust has a hole or crack,  you will notice a louder than normal driving experience. These cracks and holes can also cause a carbon monoxide leak, so it’s essential to repair your muffler or exhaust system quickly.

The first signs that you may have a muffler or exhaust issue is a grumbling or dull tone when accelerating. This noise is caused by a muffler or exhaust manifold crack. Most of the time, this can be easily repaired; however, depending on the age or car or exhaust system condition, it can be better to replace the system.

    Catalytic Converter experts

    Another exhaust system issue is problems with the catalytic converter, which plays a vital role in a car’s exhaust system. If your catalytic converter begins to fail, you will hear loud sounds similar to shaking a metal box filled with coins while your vehicle is idle. You may also notice your check engine light is illuminated.

    Port Phillip Automotive offer catalytic converter inspections, repair and replacement, working with all makes and models of vehicles.


    You can increase your car’s life span with a healthy exhaust and muffler setup. We can help at Port Phillip Automotive because we have the best mechanics in Rosebud who are experienced in all matters related to car exhausts.


    Most people love their cars, but we often overlook the importance of the exhaust. That’s understandable ‒ we just want to get to our destination on time and in one piece, right? Travelling through the Mornington Peninsula can be pure bliss with our beautiful natural surroundings, but driving safely and carefully is of the utmost importance for you and your vehicle. If you notice any strange sounds or changes in fuel efficiency, it could be an exhaust problem.

    Your car’s fumes are created during combustion in the engine, but if these fumes seeped into the car cabin, you would suffer from carbon monoxide poisoning. This is where the exhaust comes in. The exhaust system of a vehicle is designed to keep harmful gases away from the engine and out of the cabin.

    • Exhaust manifold
    • Catalytic converter pipes
    • Muffler

    The exhaust manifold collects the expelled fumes from the engine and sends them to the catalytic converter, where they are further converted into fuel that was not combusted in the engine. The final exit point is the muffler, and the fumes escape into the air through the tailpipe. You may not realise how loud your car’s exhaust is because it’s the job of the muffler to reduce the sound of the exhaust system as it works hard to protect you during your motoring experience. A really good exhaust will also reduce carbon emissions.


    If you really want to get the most value out of your vehicle, it helps to be able to identify the warning signs that tell you when exhaust repairs are needed. If your exhaust system sounds louder than normal, it could mean that your muffler is damaged and requires professional attention. Difficulty with acceleration and sudden changes in your car’s fuel consumption are also signs of exhaust damage. However, the best way to maintain good exhaust and muffler health is by taking your car in for regular checks at the mechanic.

    When to take your car to the nearest mechanic in Rosebud:

    • Strange noises
    • Problems with acceleration
    • Abnormal fuel consumption
    • Intense driving over long periods
    • The ‘check engine’ light is on
    • Polluting emissions or darker smoke

    I was down the peninsula visiting family when my car wouldn’t start one evening. Chris from Port Phillip Automotive came and checked out the car within 20 minutes, found the problem quickly and the next day had fixed it for me. Fast, reliable and great service

    Have been through many different mechanics over the years. Chris and Port Phillip Automotive have been the best by far. An honest company that cares about their customers and always does a great job. Will definitely continue to use their services.

    My Nissan Patrol kept having engine check light come on and it would constantly go into limp mode. The car had logged several codes and Nissan told me that the car would cost approx $6000 to repair. I got a second opinion through Chris, and within 3-4 minutes he found my supposed $6000 issue, it turns it out was a loose fuel line and it was a simple fix with a $1 hose clamp. Very happy with the outcome!
