If you hear any strange noises at all coming from your exhaust or have concerns about the condition of your exhaust system, the best advice is to bring you car to us at Southlands Autocentre where our qualified exhaust specialists will be able to help you diagnose the fault and suggest an appropriate solution.
The silencer is the part of the exhaust that usually needs attention first, as it is the furthest away from the engine and is the most likely to be corroded by acidic moisture. This is because these parts remain relatively cold and give exhaust gases a chance to condense and form pools of corrosive acid inside the system. You’ll know that you have a problem with your silencer because your exhaust starts making a loud roaring noise.
Other noises to listen out for include hissing, which indicates a crack in the exhaust manifold, exhaust pipe or a leaking gasket. A chugging noise could mean a blockage in the exhaust system.
If you hear rattling under the car it could mean that the exhaust system has become misaligned. If you can hear a loud metallic vibration, it usually means that something is touching the exhaust pipe or that a clamp, support bracket or mounting is loose. Hangers and brackets hold your exhaust in place. If these become corroded, fractured or fall off completely, it can cause extra stress to the exhaust housing which can also lead to premature exhaust failure.
