1. MBRP M2220A 31″ Aluminized Quiet Tone Muffler
Looking for a high quality aluminized 31-inch muffler? Well, MBRP’s offering might be worth a look.
This is a quiet tone aluminized muffler hence, you need not worry about excruciating noise. It also reduces decibel volume by up to 10%.
It is engineered to maximize exhaust flow and minimize exhaust temperatures. This gives a boost to the efficiency of the vehicle and it performs better with a lesser amount of gas.
The bolt-on no weld design makes helps to install it very easily. It has a 5-inch inlet /outlet, an 8-inch diameter body, and overall it is 31-inch in length.
Let’s move on to the downsides.
The aluminum might peel off with time, which would expose the steel to the outer environment causing corrosion.
Nevertheless, its low oil consumption and high performance make it one of my top choices.
- Quiet tone
- Easy to install
- Consumes less gas
- if aluminum peels off the steel might corrode
2. Vibrant 1141 2.5″ Ultra Quiet Resonator
Are you looking for a stainless steel muffler that can dampen the exhaust noise? Vibrant 1141 might do the trick.
This ultra-quiet resonator has a 2.5-inch inlet/outlet and a 14-inch overall length. This straight-through muffler is constructed using stainless steel which makes it pretty sturdy.
Compared to other products of its type, the Vibrant 1141 utilizes a larger sound absorption chamber for even better sound suppression.
In most 6 cyl. and 8 cyl. vehicles provided with straight through performance exhaust systems, a rifling noise is generated. This muffler has been designed to eliminate such disturbances.
It is backed by a limited warranty of 5 years.
It does have its fair share of flaws, though.
The metal lip of the muffler might corrode with time. Also, the stainless steel makes the clumping look a bit weird.
Despite having a few drawbacks, we certainly cannot ignore the positives. In terms of the noise rating, it is one of the quietest models. The long warranty period offered by the brand is mention-worthy.
- Ultra-quiet resonator
- 5-year warranty
- Eliminates rifling noise
- The metal lip is subject to corrosion
- Clumping might look slightly tricky
3. Walker 21357 Quiet-Flow Stainless Steel Muffler
Looking for an efficient muffler that’s also easy on your wallet? The Walker 21357 might be worth a look.
This is one of the quietest models on my list. It reduces noise with the help of the OE-style louvered tubes. The OE-style domed heads help to reduce the radiated noise.
The manufacturer claims it to have a 100% stainless-steel construction. While I’m not sure—I sure can agree that it looks pretty sturdy. It has an internal drainage system that prevents the accumulation of moisture.
It comes with OE-style hangers, brackets, and pipe routings to facilitate easy installation. Temperature fluctuations are well managed by the internal partitions and mechanically joined tubes that allow expansion and contraction to minimize distortion.
It features precision fit, superior flow, and OE-style sound. The 2.25” inside diameter off-set outlet and centered inlet connections align for an easy fit. They are readily available for most domestic and import vehicles.
It has a few downsides, too.
In very few cases, customers found that the muffler leaked around the roller seams. Though if you were to ask me, it seems like they, unfortunately, received a defective piece. This should be easily fixable by requesting a free replacement.
- Quiet operation
- Easy to install
- build quality requires improvement
- in a very small number of cases, the muffler leaked around the rolled seams
4. Dynomax 17748 Super Turbo Muffler
Do you fancy a turbo style aluminized muffler for your vehicle? The Dynomax 17748 might be worth your attention.
The large internal flow tubes improve exhaust flow and reduce backpressure. It is ultra-quiet and reduces noise using the Fiberglass Matting Tech that dampens unwanted internal resonance.
The inlet/outlet diameter is 2.5 inches. Easy-fit is almost guaranteed with this product. It is able to eliminate turbulence very well.
It is claimed to flow up to 700 SCFM. SCFM stands for standard cubic feet per minute. It is the molar flow rate of a gas corrected to standardized conditions of temperature and pressure. In short, it denotes a fixed number of moles of gas.
The negative points of this product are the construction is not of excellent quality. In order to get the perfect fit, welding might be necessary which may feel a bit tedious.
- Easy to install
- Quiet operation
- Dampens internal resonance
- construction needs more attention
- welding might be required for perfect fit
The Buying Guide: Factors to Consider While Purchasing the Product
1. Noise Level
Mufflers are intended to reduce the overall noise being released from the exhaust pipes. It must be noted that not all types of mufflers reduce noise to the same extent.
It has been scientifically proven that turbo mufflers are better in muffling noise than straight-forward and chamber types.
Keeping this point in mind, in my opinion, Dynomax 17748 Super Turbo Muffler is a great pick.
2. Muffler Types
Mufflers can be broadly classified into three main types – chambered, straight-through, and turbo. All of them reduce noise by slightly different levels.
These types of mufflers are designed to allow great airflow. They have a straight, perforated pipe that is wrapped in good sound-deadening materials like fiberglass and steel wool.
It almost does not restrict the airflow at all and is ideal for race cars. These are much more compact than the rest of the types.
But the only major drawback of these types is that they are comparatively much noisier. If you go for straight-through type mufflers, then Vibrant 1141 2.5″ Ultra Quiet Resonator is worth your attention.
These mufflers tend to produce a throaty sound and hence are ideal for street machines and muscle cars. They feature inner chambers arranged at specific lengths to reflect sound waves against each other. By doing so, the sound waves tend to cancel each other and reduce the noise.
Some models may also contain other sound-deadening materials inside the chambers to further baffle noise.
The turbo type mufflers have a set of perforated tubes that move the gases in an S-shaped track. This shape causes more restriction of airflow.
But by doing so, it allows the air to travel through different sections of the tube and thus, dampen the noise. They are often considered to be a hybrid of chambered type and straight-through type.
One of the best turbo mufflers is Dynomax 17748 Super Turbo Muffler.
3. Muffler Size (Fitting)
This is one of the most important factors that must be considered when buying a muffler. Getting one, of the incorrect size, can result in a decrease in the overall performance of the engine and have a detrimental effect on fuel efficiency.
But worry not!
It is quite easy to determine what will go best with your vehicle. The first step is to check the horsepower, single or double exhaust system, and engine displacement. Depending on these factors the muffler can be bought.
You can refer to the following table to make an informed decision.
One of the best products when it comes to getting a perfect fit, as per many users is Walker 21357 Quiet-Flow Stainless Steel Muffler.
4. Aluminized Steel vs. Stainless Steel
When it comes to the material of the muffler, you are can choose from aluminized steel or stainless steel. Both have their set of advantages and disadvantages.
A muffler is expected to be sturdy enough to withstand the high temperatures and pressure. Both options are able to deal with these adversities quite well.
But aluminized steel is good when you are on a budget. They tend to more affordable than their counterpart.
The stainless steel muffler, on the other hand, is better able to resist corrosion and wear and tear which aluminized steel is not quite good at.
If you opt to go for aluminized steel mufflers than MBRP M2220A 31″ Aluminized Quiet Tone Muffler is a good choice and if you go for the stainless steel ones you may check out Walker 21357 Quiet-Flow Stainless Steel Muffler.
Frequently Asked Questions
1. Mufflers vs Resonators: What’s the Difference?
The only difference between the two is that mufflers are crafted to decrease the overall noise across all the RPM (Revolutions per Minute) whereas the resonators baffle resonance only at a particular RPM.
2. Will a Bigger Muffler be Quieter?
Generally, the more the volume, the quieter is the muffler, Hence keeping this fact in mind it can be said that a bigger muffler tends to create lesser noise.
