Aside from reducing the harmful substances from the waste gases, the exhaust system is also the structure that reduces the noise coming from the engine. Noise reduction is specifically a responsibility of the muffler. The uncomfortable and ear-blasting roar of the engine will make its way even inside the vehicle if this component malfunctions. When this happens, a car owner doesn't have any other choice but to find a new Center Muffler replacement. The center muffler, also referred to as the main muffler or silencer, is where the actual noise cancellation takes place. Driving with noise blasting the interior is a very unpleasant thing. No one will be able to tolerate it for a long period of time, which makes replacement a must. Generally, central mufflers vary in size so a car owner must be shrewd enough to know what size fits his specific vehicle make and model. Some are custom-made to fit a vehicle accurately, which makes installation very easy and fast. Installing a brand-new Center Muffler is very beneficial indeed if one wants to preserve the comfortable and relaxed atmosphere inside his vehicle. The center muffler is made from durable materials enabling it to provide long service life. Finding a high-quality Center Muffler is easy since a large number of this part abounds in automotive shops whether local or online.
Resonator Buyer's Guide
- Engines emit a lot of sounds at different frequencies. Resonators are designed to cancel out certain frequencies of sound produced by the exhaust system.
- Resonators and Mufflers are two different parts that both work in the same system. Mufflers are responsible for noise reduction while resonators don’t affect the overall volume or the exhaust note. Resonators reduce drone and provide a smoother exhaust note.
- If your vehicle comes already equipped with a resonator, it’s a good idea to familiarize yourself with the symptoms of a malfunctioning resonator. Not only will it help you decide when to replace your vehicle’s resonator, but it also will help you spot problems with this part before it gets worse.
- Before buying a replacement resonator, you need to consider the compatibility and material of the replacement part that you’re going to buy. Getting an OE replacement is the best choice because you’ll get a high-quality replacement for a price that won’t break your bank.
- A replacement resonator can cost you anywhere from #35 to a bit less than $400. The price largely depends on the part’s brand, replacement type, quantity, material, and compatibility with your vehicle’s year, make, and model.
A good vehicle isn’t only defined by its performance and aesthetics. The distinct but pleasant roar of an engine means that it is well-maintained and is in top shape. Sometimes, though, the sound of an engine or the exhaust system doesn’t sound good at all. This makes you wonder if any of your car’s components is faulty or broken.
You check your vehicle and you find that you need an exhaust resonator replacement. What is a resonator and why do you need it? This guide will take you through the process of choosing the right replacement resonator for your vehicle’s exhaust system.
What is an exhaust resonator?
An exhaust resonator is a device that exhibits resonant behavior. When a sound wave enters the resonator, a part of it goes through the whole chamber, while a part of it gets reflected off. A resonator is designed such that the high-pressure part of the wave that went through the chamber lines up with the low-pressure part of the wave that got reflected off. This cancels both parts of the wave out.
Engines emit a lot of sounds at different frequencies. Resonators are designed to cancel out certain frequencies of sound produced by the exhaust system. Their internal structure is designed to cancel out the sound waves produced by the exhaust system using the sound waves reflected by the resonator.
Resonator vs Muffler
Resonators and Mufflers are two different parts that both work in the same system. Mufflers soften the exhaust note and bring it to a particular tone. However, even after the Muffler has softened the exhaust sounds, there could still be a leftover exhaust drone at certain RPMs. Resonators are built to cancel out the leftover, unwanted resonance, or drone. To put it simply, mufflers are responsible for noise reduction while resonators don’t affect the overall volume or the exhaust note. Resonators reduce exhaust drone and provide a smoother exhaust note.
Symptoms of a bad resonator
Your vehicle’s resonator is an important component of your vehicle’s exhaust system. If your vehicle comes already equipped with a resonator, it’s a good idea to familiarize yourself with the symptoms of a malfunctioning resonator. Not only will it help you decide when to replace your vehicle’s resonator, but it also will help you spot problems with this part before it gets worse. Below are just some of the signs that your resonator needs replacing.
Poor engine performance and fuel economy
A collapsed or damaged exhaust resonator can choke up the whole exhaust system and engine. This results in poor engine performance and reduced fuel economy.
Exhaust resonators can also create backpressure if they’re badly damaged or dented. The pressure can build up so much that the engine will stall or have problems starting. Excessive backpressure can also trigger oxygen sensors to read lean.
Since the resonator cannot perform its function to reduce engine drone, excessive noise will be heard coming from the engine. This usually comes off as a high-frequency buzzing sound.
A blacked-up resonator will have difficulties allowing dangerous gases to exit the exhaust system. These fumes can build up and cause a serious health hazard.
Aside from the symptoms listed above, there’s another reason to change your resonator. For some vehicle enthusiasts who are working on customization projects, adding custom exhaust systems to their vehicles allows their vehicles to accommodate the additional horsepower. Resonators will be a very important addition to those custom exhaust systems to keep the engine roaring at a pleasant note while freeing up the exhaust efficiently.
How to buy a replacement resonator
If you need to buy a replacement resonator right away, you have to take into account several factors about the part that can affect your vehicle’s exhaust performance. Below are some tips that can help you choose the right replacement resonator.
When buying a replacement resonator, you’ll need something that’s compatible with your vehicle’s year, make, and model. Choosing a direct fitting part ensures that you won’t have to spend so much time and energy during installation. If you’re going for a custom resonator, it’s best to consult a trusted mechanic or technician first before making changes to your vehicle as installing the wrong replacement part can affect your entire exhaust system.
Resonators used to be made of steel back in the 60s and 70s. However, due to new regulations, resonators need to be built to last. The most common choice of material nowadays for resonators is nickel steel alloy because they last longer. However, there are other steel alloys available in the market that are durable and long-lasting as well.
OE replacement vs OEM parts
OE replacements work as well as, if not better than, OEM parts. OEM parts are manufactured by authorized manufacturers and sold by authorized merchants, so they don’t come cheap and aren’t easy to find. With OE replacements, you can get the same quality but for an even better price. In addition, there’s more variety to OE replacements and they’re readily available at your trusted mechanic or car parts shop.
How much is a replacement resonator?
A replacement resonator can cost you anywhere from #35 to a bit less than $400. The price largely depends on the part’s brand, replacement type, quantity, material, and compatibility with your vehicle’s year, make, and model.
Replacement resonators are often made with different types of steel such as aluminized steel, stainless steel, regular steel, or 409 steel. It helps to know which kind of steel is compatible with your exhaust system and your vehicle’s overall condition and aesthetics. Resonators also differ in inlet and outlet sizes which can affect the drone cancellation. It’s best if you look at your vehicle’s specifications for a resonator to see if it matches that of the replacement part you plan on buying.
A replacement resonator is usually sold individually but can also come as a part of an assembly. You can also choose a resonator depending on its attachment type. Most resonators on the market are either bolt-on or clamp-on, while some have flanges to fasten them onto the exhaust system. There are also weld-on resonators available but you have to check first if this type is compatible with your vehicle.

The Dos and Don'ts in Picking the Right Resonator
Can you imagine yourself bearing noises from the engine operations while having a road trip? That would definitely ruin a thrilling driving experience! Hence, there is the resonator to help you out. Together with the muffler in the exhaust system, your resonator cancels out engine noises through its resonating chamber. This is gotten from the idea of an acoustic resonator, which has an exhaust note that allows the instrument to produce a pleasant tone rather than noise. Hence, if you want to buy one, you must know if it is fit for the type of vehicle that you have. Listed here are some points that you must keep in mind, so you can make a successful purchase of your resonator:
- Determine the most compatible resonator that is suitable for your vehicle. There are two basic types of resonator that are sold in the automotive market today: (1) louvered core, and (2) perforated core.
- Pick a resonator that is made from durable materials. For instance, a resonator that is made from stainless steel is slightly more expensive than the other types but it can last for a long period of time.
- Make sure that you consult a trusted technician or mechanic that can properly weld the resonator. This is because any muffler shop can get the job done, but a professional that specifies in the given area can get the job well done.
- It is recommended to purchase a resonator that is longer in length. This is because a longer chamber means that there is more space in which the noises can be canceled out.
- DON'T select a resonator that does not come from a trusted manufacturer. Some sellers might trick you into thinking that you are purchasing a resonator made from high-end materials when in fact, they just offer substandard classes. Be sure to verify the auto shop where you are about to make a purchase.
- DON'T modify the resonator in any way. Keep in mind that you must select a resonator that is compatible with your vehicle. Any unnecessary changes made to a replacement resonator can have an effect on the engine operations.
Resonator: How to Replace It
Everyone wants to have a perfect and enjoyable road trip, right? One of the things that may possibly go against your dream driving experience is engine noise. Who wants to bear annoying noises while riding, anyway? That is why your resonator is present in the exhaust system. It has an internal chamber that produces sound waves that are in charge of combating noises from the engine, which further cancels them out. It goes along with the exhaust muffler in order to get the job done. So if you start to hear loud inconvenient sounds coming from the engine while riding, then your resonator can possibly be in trouble. You must know how to replace it immediately for your own comfort. Listed here are simple steps that can help you to finish the job:
Difficulty level: Moderate
Things you'll need:
- floor jacks and jack stands
- new resonator
- emergency screws
Step 1: Have your vehicle raised off the ground with the help of floor jacks and jack stands, so you can be able to have a proper access on the part underneath your vehicle.
Step 2: Locate and remove the clamp of the air intake hose that is connected to the air filter. In this way, you will be able to easily remove the resonator that is located beneath the hose.
Step 3: Remember to place the clamp and the air intake hose on a safe area because you need to attach them again after the installation of your new resonator.
Step 4: You may now remove the screws of the resonator's clamp using the appropriate tool. After the screws are detached, your resonator can be pulled out without difficulty.
Step 5: Using a screwdriver, secure the new resonator into place firmly. If the old screws are not in good condition anymore, you can make use of the emergency screws. Reinstall the air intake hose and its clamp afterwards.
Step 6: With the support of the jack, carefully lower your vehicle while removing the jack stands. You may start the engine to test the efficiency of your new resonator afterwards.
