Exhaust Systems in Atherton

Some common signs include a louder-than-usual engine noise, rattling or hissing sounds from underneath the vehicle, poor fuel economy, a noticeable drop in engine performance, or even the smell of exhaust fumes inside the cabin. You may also notice rust, visible holes, or hanging parts under the car. These issues can develop over time due to age, moisture, or impacts with road debris. Ignoring them could lead to more serious engine damage or harmful gas leaks. If you notice any of these symptoms, it’s important to have your exhaust inspected and repaired by a qualified technician as soon as possible.

Your exhaust system should be inspected at least once a year or during your regular vehicle service. However, if you drive on rough or unsealed roads, short distances frequently, or in wet, humid conditions, your exhaust may wear out faster and require more frequent checks. Rust and corrosion are common issues, especially in systems made from mild steel. During an inspection, a mechanic will look for cracks, leaks, loose connections, and general wear. Routine checks help catch small problems before they cause major performance or safety issues. Preventive maintenance not only extends the life of your exhaust but supports overall engine health.

Yes, a damaged or inefficient exhaust system can significantly reduce your vehicle’s fuel economy. If there's a leak or blockage, your engine may have to work harder to maintain performance, using more fuel in the process. A failing oxygen sensor or catalytic converter can also cause the engine to run rich — burning more fuel than necessary. Even small leaks can lead to incorrect readings that throw off the engine's air-fuel mixture. Maintaining your exhaust system in good condition helps ensure your engine operates efficiently, which not only saves fuel but also reduces emissions and prolongs the life of related components.
