The exhaust system is a sequence of tubes that works together to transport the waste products from the engine. Basically the system is composed of exhaust pipes, header, catalytic converter, and muffler. It starts to work once the exhaust gases are collected in the header coming from the cylinder. Before the exhaust gas will be released into the open it will travel through the catalytic converter to be converted into an environment friendly substance. In the end of the process, the converted exhaust gas will be released outside the system through the use of the muffler.

The exhaust system is a very important part of your ca. It greatly influences the performance of the engine system because this is where it breathes and release unwanted gases to perform well. Unfortunately, the exhaust system is placed in an environment with high temperature, its components will definitely becomes a subject of deterioration in due time. No matter how well you maintain them eventually it will wear out. Thus, every once in a while you need to diagnose problems in your car’s exhaust to make sure that it is in good condition.

Here are some of the steps I have gathered in the net to serve as a basis for you to have a healthier car with a problem-free exhaust system!

Examine the length of the exhaust system, starting at the engine and continuing back toward the tailpipe.

  1. Look for signs of cracks along the pipes, especially where the exhaust manifold connects to the cylinder and where it connects to the main pipe.
  2. Ensure that the exhaust port near the cylinder head for signs of burned or discolored paint. It’s a sign that the exhaust system is not functioning as it should.
  3. Carefully listen to the engine while it is running. You can diagnose an exhaust problem by the noises it makes: a recurring hiss or unusual popping noise is usually caused by a problem in the exhaust system. This is a sign that the muffler or the pipes are probably leaking.
  4. Look at the muffler of the car. Its surface should be shiny and solid if you want the exhaust system functioning as it should. Any signs of problems like holes, punctures, or undue rust should be carefully check if it is severe. Try to repair or eliminate such damages in the surface of the muffler to ensure good flow of exhaust gas.
  5. Thrust at any questionable pipes with a pair of pliers or the end of a screwdriver. Rot or corrosion may not always appear on the surface, but it will weaken the surface of the exhaust pipes. If you can nudge through the pipe, then it probably needs to be replaced.
  6. Start the car and check the engine’s intake manifold vacuum while it is idling. It should read about 18 inches or so. If it reads lower than that, there is probably a restriction in the exhaust.
  7. Remove the car’s catalytic converter and hold it up to a bright light. If you can see the light through it, the converter is working fine. If you can’t, it’s plugged and needs to be replaced.

The following steps if you do it carefully, you’ll surely experience a good feedback in your exhaust system. Make sure that you perform the following steps when doing general repairs and check up in your car. This will help you prevent a more serious problem in the other parts of your car because, once the exhaust system is in worst condition, engine and other system will be chocked and severely acquire damage due to toxic exhaust that which is not released out into the open.
