How long does the exhaust air pipe last?

Since 1966, car manufacturers have been forced to drastically reduce the amount of emissions that vehicles emit into the atmosphere. During this time, technology has come a long way and allowed for all sorts of advances in this area. It was in 1966 when cars began to circulate fresh air in the exhaust gases with the help of an exhaust air supply pipe. This tube connects to or near the exhaust manifold. Air is supplied to a place of high temperature, which allows combustion to occur, and then the exhaust gases exit through the vehicle's exhaust pipe.

Because this tube is exposed to extremely high temperatures, it may crack, leak, or break. It can also get blocked over time. As soon as the tube stops working properly, it will need to be replaced immediately. Here are some signs that your exhaust air tube has reached its end of life and needs to be replaced by a professional mechanic.

• Do you smell fuel from the exhaust pipe? This may mean that the tube is leaking, cracked, or broken. You don't want to leave this issue as it will affect your fuel efficiency. Also, the longer you leave the pipe out of service, the higher the risk of damage to your engine parts.

• If you start to hear a lot of noise from under the hood on the exhaust, this is another important sign that it's time to replace the air supply pipe.

• There is a good chance that you will not be able to pass the emissions or smoke test if the exhaust air supply pipe is not working.

• It is also recommended that if you are checking and servicing the EGR valve, you also have a mechanic inspect the exhaust air supply pipe.

The exhaust air pipe is important in minimizing the amount of emissions your vehicle emits. Once this part reaches its expected life, your fuel efficiency will suffer, you will fail your emissions/smog test and you risk damaging your engine. If you experience any of the above symptoms and suspect that your exhaust air tube needs to be replaced, have a diagnosis or have an exhaust air tube replacement service from a professional mechanic.
