Located on the underside of your vehicle, the exhaust system is responsible for collecting and directing harmful emissions away from the vehicle, reducing the number of pollutants released into the environment, and minimizing engine exhaust noise and force. The exhaust system is composed of pipes and tubing designed to streamline vehicle operation while maximizing vehicle performance and efficiency.

Engines produce dangerous gases as a byproduct of the combustion process. The exhaust manifold collects the emissions from the engine and funnels the gases through the front pipe to the catalytic converter. The converter transforms these harmful gases, like carbon monoxide, hydrocarbons, and nitrogen oxide, into less harmful ones, like oxygen, nitrogen, water vapor, and carbon dioxide. The muffler helps cancel out the noise created by the engine. The muffler dissipates sound waves while the tailpipe releases the converted gases into the atmosphere.

Depending upon the problem, the exhaust system can affect both your vehicle’s performance and your ability to drive. For these reasons, it is important to keep current with maintenance intervals on your exhaust system. A repair service may be impending if you hear excessively loud noises during acceleration. These noises may be a sign of holes or cracks somewhere in the exhaust system. Rattling noises when starting the vehicle or excessive idling may be a sign of failed or broken hangers.

If you feel drowsiness while driving, this may be a serious sign that fumes are leaking through the vents and into the cabin interior. Sharp odors are also signs that noxious fumes are leaking into the vehicle. Signs of rust or cracks in any component of your exhaust system indicate corrosion. If you experience any of these symptoms, you should seek a service sooner than later.

Maintaining routine exhaust system services will help keep all your exhaust components, like the exhaust manifold, front pipe, downpipe, catalytic converter, and muffler, working efficiently. Routine maintenance on your exhaust system will save you from having to replace the entire exhaust system down the road.

The Basics of Catalytic Converter Replacement at Logan's Import Service Emporium

Located on the underside of your vehicle, the catalytic converter helps clean up vehicle emissions before expelling them into the environment. Catalytic converters contain honeycomb-like structures coated with platinum and palladium that help minimize the harmful effects of carbon monoxide, hydrocarbons, and nitrogen oxide produced by your vehicle’s engine. These harmful elements pass through two stages: the reduction catalyst stage and the oxidation catalyst stage. During the reduction catalyst stage, nitrogen oxide is converted into oxygen and nitrogen gases while carbon monoxide and hydrocarbon is oxidized in the oxidation catalyst stage. The catalytic converter also relies on the oxygen sensor to detect the correct level of oxygen introduced in the oxidation catalyst stage. Routine exhaust system maintenance can help ensure your catalytic converter is always working optimally and reduce the likelihood of it releasing harmful and often deadly chemicals into the environment, or into the cabin of your vehicle.

Why Should You Have Catalytic Converter Replacement Services Performed by Us?

Because of the role they play in passenger safety and emission control, catalytic converters are important exhaust system components. Without a catalytic converter, your exhaust system would release poisonous and dangerous gases, like carbon monoxide, hydrocarbons, and nitrogen oxide. A damaged catalytic converter must be replaced at the first sign of trouble.

Clogged catalytic converters are also dangerous. If you try to accelerate but your vehicle fails to speed up, the catalytic converter may be clogged, which will quickly cause your engine to fail. The smell of sulfur also indicates a bad catalytic converter. A damaged oxygen sensor can lead to the catalytic converter operating less efficiently and reducing its lifespan. If there is not enough oxygen, the harmful gases will fail to diminish, while too much oxygen can cause the converter to overheat and fail.

Our service staff will conduct tests to determine the exact cause of a malfunctioning catalytic converter.

The Basics of Center Exhaust Section Replacement at Logan's Import Service Emporium

The center exhaust section contains the catalytic converter and the section of exhaust pipes between the downpipe and the tail pipe. The pipes in the center section of your exhaust system are shaped to connect to each other while wrapping and bending to accommodate other parts and components on the underside of your vehicle. The harmful emissions converted by the catalytic converter into less harmful elements are carried away from passengers by the exhaust pipes.

Your vehicle’s center exhaust section also contains the oxygen sensor, which determines the correct level of oxygen introduced during the conversion of these harmful emissions into less harmful elements by the catalytic converter. Maintaining proper center exhaust section performance will ensure that your entire exhaust system continues to minimize exhaust noise and reduce pollutants released into the environment. Center exhaust system maintenance is important for your safety, the safety of your passengers, and overall vehicle maintenance.

Why Should You Have Center Exhaust Section Replacement Services Performed by Us?

A center exhaust system may need to be replaced for a few reasons. The catalytic converter may be failing. Pipes may be corroded or clogged. Because the catalytic converter is tasked with converting the harmful emissions of carbon monoxide, hydrocarbons, and nitrogen oxide into less harmful elements like oxygen, nitrogen, water vapor, and carbon dioxide, a clogged catalytic converter may mean that these harmful and deadly gases are being released into the cabin of your vehicle. A clogged catalytic converter will result in a loss of vehicle acceleration, low gas mileage, and stalling. A completely clogged catalytic converter or exhaust pipes will cause exhaust backpressure and the failure of your vehicle’s engine.

Routine center exhaust system inspections can prevent breakdowns and ensure proper exhaust system operating conditions. Being wary of the warning signs for impending center exhaust section issues can help you determine the proper time for replacements.

The Basics of Downpipe Replacement Services at Logan's Import Service Emporium

The exhaust system is responsible for converting engine emissions into less harmful gases before releasing those gases into the atmosphere. The downpipe or front section of an exhaust system connects the exhaust manifold to the catalytic converter. The manifold collects, diminishes, and funnels emissions to the catalytic converter, which converts the emissions into even less harmful substances. Downpipes are designed with a large diameter so that gases can be quickly transferred between exhaust system sections without delay.

Without a properly functioning downpipe, the performance and efficiency of the entire exhaust system would be compromised. Your vehicle’s performance is affected when the channel of pipes comprising the exhaust system is inhibited in a way that prevents proper expulsion of the emissions created during the engine combustion process. Replacing your downpipe at the first sign of trouble will promote exhaust system maintenance and improve engine performance.

Why Should You Have Downpipe Replacement Services Performed by Us?

Common problems with downpipes often result from leaks and internal corrosion. Worn exhaust system components, like the downpipe, should be replaced at the first sign of trouble. Most aftermarket downpipes are larger in diameter than the original equipment pipes they replace. Therefore, replacing your downpipe with an aftermarket downpipe can significantly reduce restrictions and positively impact engine horsepower.

Improving the efficiency of the pipes composing the exhaust system will ultimately improve the condition of your engine and the performance of your vehicle. Likewise, blockages and other damages to exhaust system components will negatively impact engine performance. Louder than usual noises and problems accelerating are all signs that your vehicle’s exhaust system may be damaged.

The Basics of Exhaust Inspection Services at Logan's Import Service Emporium

The exhaust system collects the harmful emissions released from your engine and directs them away from the vehicle. Exhaust system components work together to reduce the number of pollutants expelled into the environment.

The manifold collects the mixture of air and fuel from the engine and burns unused fuel. From the manifold, the emissions are sent through exhaust pipes into the catalytic converter, where the harmful elements are reduced and converted into less harmful gases in a honeycomb structure coated with platinum, rhodium, and palladium. These gases travel into the muffler, which dampens noise and dissipates the sound waves created during the combustion process in the engine. Finally, the gases are released into the environment through the tailpipe.

Periodically checking these components for damage will help keep your exhaust system operating at maximum efficiency.

Why Should You Have Exhaust Inspection Services Performed by Us?

Because the exhaust system is responsible for controlling your vehicle’s emissions, an inspection of the exhaust system is critical for your safety and the performance of your car. An exhaust system leak is dangerous due to the release of carbon monoxide into the cabin compartment, which can affect your judgment and perception.

Exhaust noise is usually a sign of trouble, and should never be ignored. Blockages and plugged components can cause a loss of power and poor fuel economy. Leaks are often a result of internal corrosion, which is why close, routine inspection of your exhaust system is extremely important for overall car maintenance. Mounting components and gaskets will also be inspected and replaced as needed.

During an exhaust service and inspection, all components, including the muffler, catalytic converter, manifold, downpipe, and exhaust pipes, are visually inspected for damage and tested for proper working order.

The Basics of Manifold Replacement Services at Logan's Import Service Emporium

In your vehicle’s exhaust system, the manifold collects harmful emissions produced by the engine during the combustion process. The exhaust manifold is the first compartment to receive these gases from the engine’s cylinders. The manifold collects the harmful gases produced during the combustion process. The manifold contains an oxygen sensor that tells the engine control computer to increase or decrease the amount of oxygen in the fuel and air mixture assembled during the combustion process. After the leftover gases are collected in the manifold, the manifold funnels these gases into the rest of the exhaust system. Over time, this process of heating and cooling can eventually take its toll on the manifold.

Why Should You Have Manifold Replacement Services Performed by Us?

A manifold replacement may be necessary if corrosion or other damage is found by a member of our service staff. Be wary of ticking sounds coming from underneath your vehicle. This could be a sign that your manifold is loose and bumping against other components in the exhaust system. A leak in your manifold will result in poor engine power and performance. Engine hesitation and hard acceleration are signs of problems with your manifold. Increased noise and sputtering indicate manifold damage.

Consider scheduling an inspection of your manifold at the first sign of trouble. If leaks or damage are detected during a service, your manifold will be replaced. Routine inspections of your vehicle’s exhaust system can prevent your manifold from failing and potentially allowing harmful fumes to reach you and your passengers.

The Basics of Muffler Replacement Services at Logan's Import Service Emporium

As part of the exhaust system, the muffler is responsible for dampening engine noise and releasing vehicle emissions into the environment. All mufflers are designed to revert the pressure and emissions produced in the combustion process and keep them from entering the cabin of the vehicle.

Mufflers are commonly made of steel and coated with aluminum. There are two types of mufflers in vehicles. The first type of muffler utilizes resonating and expansion chambers to reduce noises as a result of the engine combustion process. When sound waves move through this type of muffler, high-frequency waves collide with low-frequency waves and cancel each other out, thereby eliminating noise.

The other type of muffler utilizes a perforated pipe, containing metal, fiberglass, or another sound-absorbing material. Maintaining optimal muffler performance is a must if you aim to protect your passengers from harmful emissions while keeping the operation of your vehicle relatively quiet.

Why Should You Have Muffler Replacement Services Performed by Us?

Like most vehicle components, routine visual inspections can promote proper muffler maintenance, but there are signs to be aware of when considering the likelihood of a muffler replacement. Sometimes muffler repair may be necessary to replace a broken clamp or clasp, but over time, through periods of heavy use, mufflers may rust and rot. Other times, a muffler may be damaged by road debris.

Vibrations coming from the muffler are a sign of loose hanger mounts. Vibrations may also indicate that the sound-reducing parts have corroded and stopped working completely. Soot-covered mufflers and loud noises are sure signs of a bad muffler. A bad muffler can lead to decreased fuel efficiency and rough idling. Large clouds of smoke coming from the exhaust pipe is cause for having your muffler inspected or replaced. Our service staff can restore efficiency to your vehicle’s exhaust system by replacing a faulty muffler.
