What does an exhaust do?

The exhaust system has a number of vital and important tasks to perform, so it is crucial to keep it in good working order. During engine combustion, gases such as carbon monoxide and carbon dioxide are released. Any build up of these waste gases inside the engine could lead to excessive pressure. Excessive exhaust back pressure can prevent the proper gas and air mixture flowing into engine cylinders. The vehicle's economy and performance are then affected.

Combat Air Pollution

An efficient exhaust reduces pollutants If an exhaust isn't working properly, then excessive amounts of toxic gases can be released into the air. Some provinces now have legal limits which engines and exhaust systems must meet.

Beat Noise Pollution

Exhaust systems muffle the sound of hot gases escaping under pressure. If your exhaust is too loud you could end up with a fine. That's why exhausts are fitted with silencers which absorb and silence the sound of the escaping gases, bringing the noise levels down to legal socially acceptable standard.

Stop Leaks

Exhaust system leaks of any sort aren't good news. A leak near the hot exhaust manifold is a concern. If you suspect a leak, or even just have a doubt about your exhaust, come in to Fast Lane for a free check by our Ford-trained specialists.

Legal Requirements

The general legal requirement is that the exhaust system and muffler must be maintained in good and efficient working order. Noise levels emitted must be maintained at reasonable levels and may be gauged by a decibel meter. Exhaust gases must not escape into the atmosphere without going through a muffler.
