How can I tell if my exhaust system needs inspecting?
Most exhaust problems can be diagnosed by either listening out for loud roaring, chugging noises or by visually checking the exhaust system underneath the vehicle.
A vehicles exhaust system is designed to direct emissions away from the front of the vehicle but also to reduce noise and to improve the performance of the engine, maximising fuel consumption.
What to listen for?
The silencer is the first part of the exhaust that usually gives you a warning that there is an exhaust problem. You’ll know that you have a problem with your silencer because your exhaust will begin making a loud roaring noise that cannot be missed.
A hissing sound might indicates a crack in the exhaust manifold. Whilst a chugging noise could mean that there is a blockage.
If you hear a rattling it could mean that the exhaust system has become loose or misaligned.
What to look for?
Other problems can be identified with a visual check.
Look underneath your vehicle from the engine down to the tailpipe and look for any signs of corrosion. If the component has rusted through or is rusted from the inside it may need replacing.
A damaged exhaust system will not only produce additional noise, but it may also mean that your car’s noise levels and CO2 emissions are higher than the legal requirements. This may result in an MOT failure
Why it is important to maintain a healthy exhaust system:
The most important role of the exhaust is the channelling of noxious fumes away from the vehicle cabin. If these fumes leak into the vehicle cabin it will become extremely dangerous for yourself and for your passengers.
The exhaust produces six gases as emissions; three of these are extremely dangerous:
- Carbon monoxide
- Nitrogen oxide
- Nitrogen monoxide
The Exhaust System has many components:
- Exhaust Pipe – Exhaust tubing is generally made of steel but can also be stainless steel or aluminized steel tubing.
- Exhaust Manifold – is attached to the cylinder head and its function is to channel the cylinder exhaust, combining it into one pipe.
- Muffler – the muffler serves to quiet the exhaust down to legal levels.
- Catalytic converter – converts harmful carbon monoxide and hydrocarbons to water vapor and carbon dioxide.
