Exhaust System Inspection Service & Cost

The exhaust system plays a major role in maintaining your engine’s smooth operation, reducing environmental pollutants that reduce air quality, and muffles the noise from your engine.

If your exhaust system is leaking, it can lead to a dangerous condition where exhaust enters your car from underneath, making you and your passengers sick. It can cause irritating noise to you and other traffic around you, and your engine light may come on when your engine isn’t running efficiently due to exhaust system problems. Whenever you have exhaust system issues, they should be inspected by a mechanic.

How this system works:

The exhaust system is comprised of several components that span from the engine through to the tailpipe. Exhaust manifolds connect the exhaust ports on the cylinder head to the exhaust pipe to collect hot gases as they leave the engine. As they pass through the exhaust pipe, the gases enter a catalytic converter where they are superheated, converting unburned hydrocarbons into less harmful gasses. The exhaust then goes through a muffler where baffles reduce the volume of the exhaust to a comfortable level, then the exhaust gases exit into the air behind your car.

Any number of situations can occur that can cause your exhaust system to operate inefficiently, and consequently your car may not run properly. You may notice the exhaust noise is louder than normal, the Check Engine Light may illuminate, and the engine may run poorly. Any of these symptoms should be addressed by a professional mechanic.

Common reasons for this to happen:

  • Muffler: your vehicle’s muffler is exposed to high heat and moisture. Over time, your muffler can develop a rust hole through its body that can cause excessive noise. The exhaust pipe near the muffler can rust through as well, which is why you see mufflers by the side of the road.

  • Exhaust manifold gasket: the exhaust manifold gasket seals the exhaust manifold to the cylinder head, ensuring that there are no leaks. Over time, some cars may develop a break or crack in the exhaust manifold gasket, which will cause an exhaust leak.

  • Catalytic converter: your car’s emissions system relies heavily on the catalytic converter to burn off excessive hydrocarbons. The catalytic converter gets extremely hot to function and can potentially fail internally. This can cause back-pressure in the exhaust system that can cause your engine to run poorly and can even damage the engine. Often, failing catalytic converters have a sulfur or rotten-egg odor.

  • Oxygen sensor: to adjust your car’s air-fuel mixture, oxygen sensors are mounted in the exhaust pipe. They measure the oxygen levels in the exhaust stream to allow the engine control module to accurately change the mixture in real time. If an oxygen sensor is slow to respond or fails, your Check Engine Light will come on and your vehicle’s emissions will likely be excessive. It can also cause premature failure of the catalytic converter, muffler, and cause your engine to run rough.

How it's done:

A top-rated mobile mechanic will come to your home or office to determine the cause of your exhaust system’s symptoms. They will provide you with an in-depth inspection report of what precisely has failed and will recommend the necessary repairs to correct the problem along with a complete estimate for the repair.

How important is this service?

The exhaust system performs the vital role of reducing harmful gases that harm the environment, could make you sick, and is integral to a smooth-running engine. If your exhaust system has a leak or emissions-related failure, you won’t pass a smog test or a vehicle safety inspection. You could get sick from the fumes, and you could cause expensive damage to your engine. Have exhaust system concerns inspected right away and repaired as soon as possible.
