When to have your Automotive Exhaust Repaired

Dependent upon your automobile and its exhaust system, the expenditure for making repairs to a damaged out-of-date exhaust module can vary greatly. However, putting off exhaust repairs will cost more in the end if you do not address the problem quickly. Mufflers do more than keep your automobile quiet, they also direct exhaust fumes away from the cabin, assist engines to operate correctly, and sustain optimal fuel competence in addition to decreasing emission pollutants.


How Exhaust Systems Work

The reason for exhaust systems is to muffle the sound made by the interior combustion-engine, decrease the temperature of the exhaust, and manage the emissions that emerge from your vehicle. Cars manifest dangerous-gases during the combustion of fuel. These gases are converted into customarily harmless emissions via the catalytic-converter. Thereby, doing much less harm to the environment. A few of the dangerous gases that an exhaust system directs are:

  • Lead and additional metals
  • Phosphorus
  • Carbon monoxide
  • Carbon dioxide
  • Hydrocarbons
  • Nitrogen oxides
  • Sulfur dioxide

Things to know if you believe your car might need muffler or exhaust-system repairs:

Increased Noise

One of the clearest indications for most drivers is a loud, deep, rumbling, vibrating sound coming from their automobile. When this occurs, it is time to get it repaired. Having the exhaust repaired before the noise becomes unbearable offers the most advantage to the car owner. Postponing a much needed repair will end up costing more. This is because continued driving with a dysfunctional muffler or ghastly catalytic-converter can damage other parts of a vehicle's operating system. The problem of increased noise should be taken care of quickly. Not only will making this move save you money, you will cause fewer disturbances to your neighbors and other people on the road.

Fuel Effectiveness

If a car owner finds they need to fuel up their gas tank more frequently than usual, they should have the exhaust system checked by a professional car repair company. Besides uncomfortable vibrations, additional fuel usage is an indicator that something is not working right with your car. If the exhaust leaks, the car engine will work harder, and when the engine works harder, it needs more fuel.


If a loss of power or a new vibration occurs when driving, have the exhaust system examined by a professional. The vibration may be perceptible when you touch the steering-wheel, car seat, or foot pedals. A rumbling sound may not be obvious, depending on the dimension of the damaged section. A leak, hole, or disconnected exhaust-system element does not only cause uneasy vibrations, this could also be a sign that the engine is not performing at its best.

Catalytic Converter

One of the most expensive exhaust-system elements is the catalytic-converter. In a number of vehicles such as trucks and SUVs, the catalytic-converter could be vulnerable to theft from scrap-metal thieves. If your catalytic-converter happens to be stolen, you will instantly become aware of a deafening sound and distorted vehicle performance when starting up the vehicle. If the catalytic-converter is still there, but not operating properly, there may be sound similar to the sound of a box of rocks being shaken when the automobile is sitting while parked or waiting in traffic. If any of these issues appears, it is wise to schedule an appointment with a professional that can repair your muffler right away
