The exhaust in your car is more important than most people think. It pushes harmful gases out, keeps the engine running right, and also controls noise. When it starts leaking, things get messy. If you notice exhaust leak symptoms early, you can fix them before they burn a hole in your pocket or mess with your health.
Why Paying Attention To Exhaust Leak Symptoms Matters?
A leaky exhaust is not just a small car issue. Those fumes can sneak into the cabin, and that’s dangerous. Carbon monoxide is silent, has no smell, and can make you sick. On top of that, leaks kill fuel economy and put extra stress on the engine. Leave it too long, and you may find yourself calling a car towing service in Perth.
That’s why you need to know the warning exhaust leak signs and book a visit at a muffler shop or a car exhaust specialist in Perth the moment something feels off.

Car Exhaust Leak Symptoms You Should Watch Out For

Here are the most common signs that your exhaust is leaking and needs attention.
1. Engine Gets Noisy
If your car suddenly sounds rough, like it’s growling, it could be an exhaust leak. Cracks or holes in the muffler let gases out, making the car louder than normal. Sometimes the sound changes when you speed up or slow down, almost like a puffing or ticking noise. Don’t ignore it. Head to an exhaust shop in Perth and get it looked at before it gets worse.
2. Fuel Economy Drops
If you’re filling the tank more often, check the exhaust. Leaks can trick the oxygen sensor, making the air-fuel mix run wrong. That burns more petrol and wastes money. You may also notice the car smells richer, like it’s burning too much fuel. Small leaks add up over time and hit your wallet harder than you think.
3. Strange Vibrations
A leaking exhaust can shake things up. You might feel vibrations in the steering wheel, under the seat, or even on the pedals. It can also cause the car to feel lazy when you press the accelerator. Sometimes the floorboards even buzz or rattle a little, which is easy to mistake for tire issues. If it keeps happening, get it checked.
4. Rust or Holes Under the Car
Take a quick look under your car now and then. If you see rust, cracks, or parts hanging low, that’s a clear exhaust pipe leak symptom. Get the exhaust pipe leak symptoms fixed before they break off completely. Rust usually starts around joints and welds because water collects there. In older cars, the muffler often rusts out first. Holes let gases escape, and over time they make the system weaker. Once one part is eaten away, the damage can spread to nearby pipes. Don’t wait for it to snap off on the road. A small patch job today saves you the cost of replacing the entire exhaust later.
5. Smell of Exhaust Inside
This one is serious. If you smell exhaust fumes in the cabin, stop driving. It means gases are finding their way in. Sometimes it sneaks in through the vents, especially when the windows are up. Call a car exhaust repair Perth or a tow truck in Australia and fix it right away. Breathing those fumes can make you feel sick and dizzy in minutes.
6. Exhaust Pipe Hanging or Dragging
Sometimes the problem is just broken hangers. The pipe may drag, rattle, or knock against the car’s frame. Even if it seems small, it can turn into bigger trouble. Loose parts bang around and can bend other sections of the exhaust. It’s also risky if it catches on the road surface while driving.
7. Engine Misfiring or Struggling
A few exhaust gasket leak symptoms can mess with exhaust flow. That shows up as misfires, jerking, or a loss of power. Don’t wait. Get to a car exhaust shop in Perth and let the mechanics sort it. The longer you drive with it, the more damage it can cause to the engine’s performance and fuel system.
What Happens When You Ignore a Leaking Exhaust?
- You breathe toxic fumes. Not safe.
- Fuel costs go up because the car burns more.
- The engine struggles harder and wears down faster.
- Loud exhaust noise can even get you fined.
- Fixing it early at a car repair shop saves money and trouble.
What to Do If You Notice Exhaust Leak Symptoms?

- If you smell fumes, stop driving. Don’t risk it. Call for a tow truck in Australia.
- If you’re buying a used car, always ask for a pre purchase car inspection. Leaky exhausts hide under the body.
- Visit a car exhaust specialist in Perth. They’ll find cracks, rust, or gasket leaks in no time.
- Pick a good muffler shop. Get the effects of leaking exhaust pipe repair done before the issue spreads.
Final Thoughts
Exhaust leak symptoms are easy to miss at first but can get dangerous fast. A noisy engine, shaky pedals, or fuel smell should never be ignored. If you suspect your exhaust is leaking, head to a car exhaust shop Perth, get a pre purchase car inspection if needed, or call for auto repair services. Don’t wait until you need a tow truck in Australia—fix it before it gets worse.

FAQs About Exhaust Gas Leak Symptoms
1. What’s the first thing I’ll notice if the exhaust leaks?
Answer: 1
Most people hear the car get louder, sometimes like a deep growl or a strange hiss. Fuel use can suddenly get worse too. In some cases of exhaust gas leak symptoms you’ll smell fumes inside the cabin, which is a red flag.
2. Is it safe to drive with an exhaust leak?
Answer: 2
It might move, but safe? No. Even a small crack can let gases out in the wrong place. The car runs rougher and you waste money on fuel. If the fumes creep into the cabin, it can make you dizzy or sick. Pull over if that happens.
3. How much does it cost to repair the exhaust in Perth?
Answer: 3
There isn’t one set price. A tiny patch job at a muffler shop can be fairly cheap. If the whole exhaust pipe needs to be replaced, then the bill climbs higher. Older cars with rust can take longer to fix, which means extra labour cost. Always ask for a quote first.
4. Can the engine get damaged?
Answer: 4
Yes it can. Leaks throw off the sensors and mess with the air and fuel mix. That can cause misfires, more heat, and even harm the catalytic converter if left too long. Engines like balance, and a leaking exhaust ruins that balance.
5. Where do I go for repairs?
Answer: 5
Take it to a car exhaust shop in Perth or a car mechanic Perth you trust. Some people try DIY fixes with tape, but that’s only temporary. A proper repair or replacement is the only way to keep the car safe. If you’re stuck on the road, call a tow truck in Australia and get it to the workshop.
6. How do I prevent leaks in the future?
Answer: 6
Check under your car once in a while. Don’t drive through deep water that can rust the pipes faster. Regular servicing at car repair shops helps spot small cracks before they turn into big holes. And if you hear new noises, don’t ignore them.
