Is your exhaust fully functioning? About your Exhaust
Your exhaust emissions system is the only means of channeling away hazardous fumes that are generated by your engine, such as carbon monoxide. An exhaust that has failed can lead to fumes being drawn into the vehicle cabin – prolonged exposure to exhaust fumes can make you feel drowsy and, therefore, more susceptible to accidents.

A healthy exhaust system is critical to maintain the health of you and your passengers, a quiet smooth running engine and optimum fuel efficiency.

How to tell if there is a problem

If your exhaust starts to make a loud roaring noise, then it is likely that there is a problem with your silencer. It is usually the part of the exhaust that needs attention first, as it is the furthest away from the engine and is the most likely to be corroded by acidic moisture.

You may hear a hissing noise, 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.

A rattling under the car 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, so corroded, fractured or missing hangers or brackets can cause extra stress which can also lead to premature exhaust failure.

You can identify many problems with a visual check. External rust may not be as serious as it first appears, because it may only be on the surface. Cracks in the pipe, or holes around seams and joins between pipes, however, can be a sign of bigger problems.

If you notice any of the above signs then get your exhaust checked out immediately.
