What is a muffler?
A muffler ( North American and Australian English) or silencer ( British English) is a device for reducing the noise emitted by the exhaust of an internal combustion engine —especially a noise-deadening device forming part of the exhaust system of an automobile.
What is a tailpipe muffler?
Dual tailpipes attached to the muffler on a passenger car to reduce the sound produced. Mufflers are installed within the exhaust system of most internal combustion engines. The muffler is engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting.
What is a muffler on a Ducati motorcycle?

Why was the muffler invented?
The muffler is engineered as an acoustic device to reduce the loudness of the sound pressure created by the engine by acoustic quieting.
Do all cars have mufflers?
Every vehicle on the road today has a muffler and exhaust system. Both components serve multiple roles in your car, but the most important roles often include reducing engine noise and remove the harmful gases and other emissions that come from your car's engine.
Why is a muffler called a muffler?
It's in the name. Mufflers are responsible for muffling the sound created by a vehicle's engine. Engines need to generate a ton of power, and, as a result, they create numerous pulsating sounds that reverberate through the exhaust valves. Thousands of these pulses are created every single minute.
Why do people love loud exhaust?
A Thrilling Drive The louder the sound, the greater the thrill. They know their vehicle is standing out. The engine noise also gives them something to play with and feel sporty even if they're just driving through traffic. To achieve this, some individuals even attach a performance exhaust to a regular car.
Why do people straight pipe their cars?
Less pressure on your engine results in more efficient operations, so you'll see a slight increase in fuel efficiency. Also, with less back pressure, the engine produces more horsepower and torque. Many drivers who race their cars see this as the primary reason to install straight pipes.
Will no muffler hurt my engine?
Your broken muffler can reduce the effectiveness of your exhaust system. The broken part can keep your car from being effective when siphoning the exhaust fumes out of your engine and will negatively affect your car engine's performance. In turn, your car will produce higher emissions and lose fuel economy.
Do cars run better without mufflers?
When you put something in the way of the escaping exhaust--like a muffler or catalytic converter--some of the engine's power must be used to push the exhaust through those devices. So if you remove them, more of the power can be used to make the car go. That means faster acceleration, and more miles per gallon.
Do mufflers add horsepower?
Do mufflers add horsepower, or is that just a myth? Reviewed by Shannon Martin, Licensed Insurance Agent. We're sorry you need to replace your muffler. But yes, it's true: mufflers do add horsepower, increasing engine performance by as much as 10 percent or even more, depending on a lot of variables anyway.
Is straight pipe or muffler better?
Straight pipes offer better flow than many popular performance mufflers. This can be helpful if you're trying to maximize performance and fuel mileage. However, high quality performance mufflers such as Paradox Performance Mufflers offer flow just as good -and sometimes better- than straight pipes.
Is a car loud without a muffler?
Without the muffler, your car's engine will be pretty loud and obnoxious. Engines need to generate a substantial amount of power, and, as a result, they create various sounds that echo through the exhaust pipe. The purpose of the muffler in the exhaust system is to reduce the sounds that the engine makes.
Why are mufflers stolen?
Why They're Stolen. Money is the main reason catalytic converters are often stolen. They contain three metals that aid in the chemical reaction that makes exhaust pollutants less harmful: platinum, palladium and rhodium. The prices of these metals have risen dramatically during the early 21st century.
What is a muffler designed for?
An effective muffler will reduce the sound pressure of the noise source to the required level. In the case of an automotive muffler the noise in the exhaust system, generated by the engine, is to be reduced.
What is the purpose of the exhaust system?
Your vehicle's exhaust system has four main functions: control noise, carry away gases, improve engine performance and improve fuel consumption.
Why do people delete muffler?
There are two main benefits of deleting the muffler. This modification will provide your vehicle with a more aggressive exhaust sound and can even improve horsepower for some vehicles.
What is a catalytic muffler?
Known as silencers in other parts of the world, catalytic mufflers quite literally “muffle” the noise stemming from the exhaust of internal combustion engines while simultaneously reducing their pollution. Learn about the history of this essential vehicle component to increase your auto part knowledge.
When was the baffle system invented?
A Baffle System. The first version of the car muffler was created by Milton Reeves of the Reeves Pulley Company in the late 1800s. It was invented in response to the exceedingly loud vehicles that disrupted communities, annoyed residents, and frightened horses. The baffle system Reeves created in 1896 quieted vehicle engines considerably.
When did mufflers become electronic?
Electronic mufflers came about in the 2000s and featured noise-canceling technology similar to what is used in noise-canceling headphones. Despite the changes the muffler has undergone, its value in terms of reducing air and noise pollution has never diminished.

What was the name of the Roman winter glove?
In Medieval Latin we find the word muffulae, defined by Du Cange as chirothecae pellitae et hibernae ("leather winter gloves"). He quotes from a cartulary of the year 817, of the issuing to monks of sheepskin coverings to be used during the winter. These may have been, as the Roman certainly were, separate coverings for each hand, although the cartulary cited also distinguishes the glove for summer from the muffulae for winter wear. The Old French moufle meant a thick glove or mitten, and from this the Dutch mof, Walloon mouffe, and thence English "muff", are probably derived.
What is handlebar muff?
Handlebar muffs are a utility product for motorcycles and scooters to provide increased comfort in adverse weather conditions , to protect the rider from rain and wind chill . With UK commercial-availability in the early 1960s, they are still available in three variations from a UK merchandiser of motorcycle accessories, including dedicated-types for small motorscooters.
What is a muff?
Muff (handwarmer) A muff is a fashion accessory for outdoors usually made of a cylinder of fur or fabric with both ends open for keeping the hands warm. It was introduced to women's fashion in the 16th century and was popular with both men and women in the 17th and 18th centuries. By the early 20th century, muffs were used in England only by women.
What is a muff made of?

Who invented the hippo hand?
Writing at his website in December 2010, American motorcycle design innovator Craig Vetter claimed to have "created and developed" from 1971 what he called Hippo Hands, later sold to the public from 1973 by the Vetter organisation. These were very similar to a product that was easily available to UK motorcyclists from retail shops/mail order outlets from 1957, with the description handlebar muffs.
What is the resonator in a car exhaust?
Some cars, especially luxury cars where quiet operation is a key feature, have another component in the exhaust that looks like a muffler, but is called a resonator. This device works just like the resonator chamber in the muffler -- the dimensions are calculated so that the waves reflected by the resonator help cancel out certain frequencies of sound in the exhaust.
How does a muffler reduce sound?
The body of the muffler is constructed in three layers: Two thin layers of metal with a thicker, slightly insulated layer between them. This allows the body of the muffler to absorb some of the pressure pulses. Also, the inlet and outlet pipes going into the main chamber are perforated with holes . This allows thousands of tiny pressure pulses to bounce around in the main chamber, canceling each other out to some extent in addition to being absorbed by the muffler's housing.
What happens when a wave hits a hole?
When a wave hits the hole, part of it continues into the chamber and part of it is reflected. The wave travels through the chamber, hits the back wall of the muffler and bounces back out of the hole.
What part of the wave will line up with the low pressure part of the wave that was reflected off the outside of?
Ideally, the high-pressure part of the wave that came from the chamber will line up with the low-pressure part of the wave that was reflected off the outside of the chamber wall, and the two waves will cancel each other out.
When did Karim Nice write "How Mufflers Work"?
Karim Nice "How Mufflers Work" 19 February 2001.
Is a resonator a mixture?
Advertisement. In reality, the sound coming from the engine is a mixture of many different frequencies of sound, and since many of those frequencies depend on the engine speed, the sound is almost never at exactly the right frequency for this to happen. The resonator is designed to work best in the frequency range where the engine makes ...
What is an exhaust manifold?
Exhaust manifold ( chrome plated) on a car engine. Muffler and tailpipe on a car. An exhaust system is used to guide reaction exhaust gases away from a controlled combustion inside an engine or stove. The entire system conveys burnt gases from the engine and includes one or more exhaust pipes. Depending on the overall system design, ...
How to increase power output?
A common method of increasing the power output of an engine is the use of upgraded headers . The increased power output is often due to a result of a larger cross-section area of the pipes (reducing the resistance on the exhaust gasses) and/or designing the pipe lengths so that the pressure wave assists in exhaust scavenging. For inline-four engines and V8 engines, exhaust manifolds are usually either a 4-2-1 design (where the four pipes merge into two, followed by a separate merge of these two pipes into one) or a 4-1 design (where the four pipes directly merge into one).
How to reduce back pressure?
Back pressure is most commonly reduced by replacing exhaust manifolds with headers, which have smoother bends and normally wider pipe diameters.
What is the exhaust system on a motorcycle made of?
Aftermarket exhausts may be made from steel, aluminium, titanium, or carbon fiber. Motorcycle exhausts come in many varieties depending on the type of engine and its intended use.
What is a chimney?
A chimney serves as an exhaust pipe in a stationary structure. For the internal combustion engine it is important to have the exhaust system "tuned" (refer to tuned exhaust) for optimal efficiency. Also this should meet the regulation norms maintained in each country.
What is the purpose of exhaust pipe?
An exhaust pipe must be carefully designed to carry toxic and/or noxious gases away from the users of the machine. Indoor generators and furnaces can quickly fill an enclosed space with poisonous exhaust gases such as hydrocarbons, carbon monoxide and nitrogen oxides, if they are not properly vented to the outdoors. Also, the gases from most types of machines are very hot; the pipe must be heat-resistant, and it must not pass through or near anything that can burn or can be damaged by heat. A chimney serves as an exhaust pipe in a stationary structure. For the internal combustion engine it is important to have the exhaust system "tuned" (refer to tuned exhaust) for optimal efficiency. Also this should meet the regulation norms maintained in each country. In China, China 5; In European countries, EURO 5; In India, BS-4, etc.,
Why did cars have two outlets?
In the late 1950s in the United States manufacturers had a fashion in car styling to form the rear bumper with a hole at each end through which the exhaust would pass. Two outlets symbolized V-8 power, and only the most expensive cars (Cadillac, Lincoln, Imperial, Packard) were fitted with this design. One justification for this was that luxury cars in those days had such a long rear overhang that the exhaust pipe scraped the ground when the car traversed ramps. The fashion disappeared after customers noted that the rear end of the car, being a low-pressure area, collected soot from the exhaust and its acidic content ate into the chrome-plated rear bumper.
What is a cutaway silencer?
A silencer, also known as a sound suppressor, suppressor or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report (sound of a gunshot) and the recoil when a gun ( firearm or air gun) is discharged, by modulating the speed and pressure of the propellant gas from the muz zle ...
What is a silencer in firearms?
A case of silencers produced by Gemtech. A silencer, also known as a sound suppressor, suppressor or sound moderator, is a muzzle device that reduces the acoustic intensity of the muzzle report (sound of a gunshot) and the recoil when a gun ...
Why do silencers reduce muzzle flash?
Because the internal baffles will slow and cool the released gas, silencers also eliminate the muzzle flash. This is different from a flash suppressor, which reduces the amount of flash by dispersing burning gases that are already released outside the muzzle, without necessarily reducing sound or recoil.
Why are suppressors not cleaned?
Wipes, packing materials, and purpose-designed wet cans have been generally abandoned in 21st-century suppressor design because they decrease overall accuracy and require excessive cleaning and maintenance. The instructions from several manufacturers state that their suppressors need not be cleaned at all. Furthermore, legal changes in the United States during the 1980s and 1990s made it much more difficult for end-users to legally replace internal silencer parts, and the newer designs reflect this reality.
Why use a suppressor on a rifle?
The most important advantage of a suppressor is the hearing protection for the shooter as well as their companions . Many hunters have suffered permanent hearing damage due to someone else firing a high-caliber gun too closely without warning. By reducing noise, recoil and muzzle-blast, it also enables the firer to follow through calmly on their first shot and fire a further carefully aimed shot without delay if necessary. Wildlife of all kinds are often confused as to the direction of the source of a well-suppressed shot. In the field, however, the comparatively large size of a centerfire rifle suppressor can cause unwanted noise if it bumps or rubs against vegetation or rocks, so many users cover them with neoprene sleeves.
How do spacers work in silencers?
Spacers separate baffles and keep them aligned at a specified distance from one another inside the silencer. Many baffles and spacers are manufactured as a single assembly and several suppressor designs have all the baffles attached together with spacers as a one-piece helical baffle stack. Modern baffles are usually carefully shaped to divert the propellant gases effectively into the chambers. This shaping can be a slanted flat surface, canted at an angle to the bore, or a conical or otherwise curved surface. One popular technique is to have alternating angled surfaces through the stack of baffles.
What rifles use a flash suppressor?
Military rifles such as the M16 or M14 often use quick-detach suppressors that use coarser than normal threads and are installed over an existing muzzle device such as a flash suppressor and can include a secondary locking mechanism to allow the shooter to quickly and safely add or remove a sound suppressor based on individual needs.
