However, most car owners don’t give their vehicle’s exhaust system a second. That is until they hear a loud popping, exhaust hiss, or rattling noise that’s pretty scary coming from the back of your car or truck. On top of that, there are health and safety concerns from exhaust fumes. You can almost bet that by the time they get to that point, they’ll be hit with a big bill for muffler or exhaust system repair. Is there a way that most motorists can extend the life and drivability of their exhaust and muffler system(s)?
Basically put your car or truck exhaust system which includes the exhaust manifold, muffler, connecting pipes and in some cases a resonator. Any car made in the last 30 years will definitely have a catalytic converter you can bet on. Single exhaust configurations use a single tailpipe exhaust manifold, muffler assembly, and tailpipe that extends just below the rear bumper, while a dual exhaust system arrangement uses two pipes. exhaust and a muffler assembly along with two resonators, two tailpipes Each assembly is connected to its own exhaust manifold and carries the exhaust gases to the rear of the vehicle.
The life of mufflers and pipes depends largely on the type of service in which the vehicle is used. If it is driven primarily in stop-start city traffic with few trips exceeding five miles, you can bet the muffler will soon rust, have a shorter lifespan, and the car owner will visit their local mechanic at their garage or at your dealer’s service center. Since the installation of mufflers and exhaust systems is a specialized job, many workshops, as well as car owners, often have the work done in garages and workshops that specialize in the repair and replacement of exhaust systems. and silencers.
The reason for such a short muffler life is that on short trips the mufflers and pipes will never get hot, let alone hot enough to evaporate the moisture in the system, which ultimately rusts the steel metal components. of mufflers and exhaust systems. This moisture not only adheres to metal components and is the cause of rust, but it also wears me down due to its highly acidic and more corrosive nature, mixing with leftover exhaust fumes and residue left over from the engine’s combustion process. of internal combustion. As a result, pipes and mufflers soon corrode and need to be replaced.
If the car is driven mainly on long, higher mileage trips, or mainly at good speeds on motorway trips, then conversely the mufflers and pipes to which it is connected will soon get hot enough to simply evaporate this moisture, similar to how a hot car or kettle boils water. Consequently, the corrosive action (ie oxidation and rust formation on metal parts and surfaces of the muffler) will be slowed down and retarded. Consequently, your vehicle will have its muffler and exhaust system last longer and have a longer service life.
Interestingly, it seems that the mufflers and pipes used in a single exhaust system will generally last longer than dual muffler installations because all of the hot exhaust gases are pushed through and pass through a single pipe, which is the only muffler. . As a result, in a single muffler system, temperatures generally reach a higher value sooner rather than later. Therefore, corrosive moisture has a better chance of heating up and evaporating into the atmosphere with less chance of remaining on metal surfaces and components to do its rusting job.
The general rule of thumb from car dealer service writers and experienced car mechanics is that mufflers and pipes should be replaced before they completely rust, because if there is any leakage in the system, the exhaust fumes are poisonous. and harmful to health. they will escape into the interior of the vehicle where they can potentially cause the death of occupants and passengers or a serious accident if the driver is affected by the exhaust fumes and gases.
