The exhaust note goes from deep aggression to moderate, which gives you a range of options. If your vehicle is high horsepower; then this is the one that you should go with. It works excellent on such vehicles.
And don’t even get me started on the technology. The patented delta flow technology that it features is race proven. All factors combined, this product is perfect for the daily drivers where you do not want something aggressive enough to annoy you.

2. MagnaFlow 10416 Exhaust Muffler
I will let you in on the thing you will love most about this product. It is the sporty sound it has to offer. The product would be particularly of great value to those who don’t only look forward to a good performance, but also in a low amount of money.
Let me go over all the features one by one. What comes first is the basis on which the foundation of the design has been laid. The mufflers of this brand, Magnaflow, all have an open performance design.
Moreover, this brand has its deep signature sound, which is exactly what this product will give you too.
Now let’s move on to the construction part. To give it the strength it needs, it has been constructed with stainless steel, and that is a huge plus. Also, the polished steel makes it stand out!
In the end, I would like to mention how sad it would be if the product weren’t meant for your car. Oh, wait! Here’s the deal. These mufflers are available in a wide range of sizes, so there is a good chance they will fit your vehicle! What a relief.
This product is meant especially for those who would prioritize performance over anything. Because let’s face it. We all love a sweet ride! A variety of applications is also included so you can use it in so many circumstances
3. Thrush 17651 Welded Muffler
Here comes the most cost-friendly product of this entire list. If you compare the cost to the features it is offering; your jaw will drop down to the floor. Let me tell you how.
The tone? Super aggressive. How is that possible? With the unique two-chamber design. That, combined with the material it is made of, it delivers unmatched powerful performance. The product is completely made out of aluminum.
It’s also welded fully for the sake of achieving durability. The exterior is made out of polished stainless steel. The length is also a convenient 19 inches, which means quality performance is ensured.

4. Dynomax 39510 Super Turbo Muffler Cat-Back Dual Exhaust System
What is the worst issue that muffler manufacturers have to strive to overcome? It’s turbulence. What is the issue that this product successfully managed to overcome? Then again, it’s turbulence.
Resistive forces have the potential to damage the engine a great deal and to cause faster wear and tear of the parts. This baby does not let that happen. How does it do that?
The internal flow tubes are purposefully made large enough to ease the passage of the exhaust flow, which gives the exhaust more room to pass, easily. These tubes feature exclusive flow directors.
By improving the flow, they reduce the backpressure, thus putting less strain on the engine.
But that is not just it. Every muffler has the fiberglass matting, which successfully absorbs the interior resonance. This is exactly what mufflers are for. And if this one can do it better than the others, then why not just go for it?
The most important feature for my DIYers is that it is too easy to install so you won’t have to worry about additional mechanic expenses!
If you are not the one to make any sort of compromises on the engine performance, then this is the perfect product for you to spend your money on.
A good build, combined with the structure of the pipes and the matting technology, gives optimum performance to your engine. So go out and get it right away if you love your engine!
5. Flowtech 50252FLT Red Hots Glass Pack Muffler
Get ready; you are going to be reading about the best muffler in the market for its price. Best in terms of performance as well as looks! I mean, seriously? A rebellion from the orthodox, boring looking car parts? You could show it to a toddler, and he’ll feel like he has been given a shiny new toy.
They are moving towards the more serious part of the discussion. The design is classy; the color is classy; the performance must also be classy. Well, it sure is! The material is high heat ceramic glass, and they are not just thick, but long-lasting as well.
There is another advantage; it can be cleaned quite easily. The dust and the dirt don’t stay, and whatever stays can be wiped off easily. Moreover, the polished surface protects the product from corrosion.
They hit a home run by using ceramic as the construction material. It is an insulator, so it doesn’t even heat up like the other mufflers out there. Lastly, low back pressure prevents wear and tear.
High temperatures have the potential to mess with the engines on a really serious level. So if you live in a place where the temperature is mostly hot, then this is the one that you should go for.
Because it is capable of keeping your engine cooler than any other products in the market. The bonus feature is the look! So you can have all these features, in a price that feels like a steal.
6. Dynomax 24250 Race Bullet Mini Muffler
Put your hands up for the most space-efficient muffler solution for your vehicle. And that is the dynomax race bullet mini muffler.
Designed especially for the cars with too little a space to fit a bigger muffler, this one is the best option to get one heck of a punch packed performance in a compact instrument.
So what are the features that allow it to perform so well regardless of its size?
Number one comes to the fully welded structure. This structure allows it to ensure lifelong durability. Made out of stainless steel, this piece is lightweight and has quite a compact design. All these features make it perfect for smaller cars.
Its design is unrestricted and straight through, and also track proven. What does that mean? In simpler words, it means this product is not only perfect for small cars, but it is also great for race cars!
And this is not the end of it. Every muffler features Continuous Roving Fiberglass (CRF) technology.
Simpler explanation: Due to this technology, there is a four dbA reduction of sound, which is meant to absorb the unwanted resonance, and maintenance of a deep race tone.
Who knew so much power is attainable by such an innocent-looking, tiny piece? Now the people with small cars will not have to worry about unnecessary modifications to their mufflers to be able to fit them into their car, who knows how much that affects their performance!
It gives you the perfect sound you are looking for as well, quieter than the others. You don’t even have to think twice if you have a small vehicle!
7. Cherry bomb 87522 Glass Pack Muffler
The first, official glass pack muffler. It is they who started it all. The mother of all glass pack mufflers. This is which birthed them all. And I think it deserves that title as well, due to the quality it offers.
Originally made in 1968, this brand took off and became so popular, that often people call mufflers “cherry bombs” instead of mufflers themselves.
It features it’s legendary sound, the signature mellow and deep cherry bomb sound. The design is straight through, which means minimum backpressure, minimum resistance, and maximum performance.
Weight is only 3.37 pounds. That means the body must be too tiny, right?
Wrong! The body is the standard size that fits a wide variety of vehicles. And with a little modification, it can fit any vehicle at all. But a size so light? Is it impossible to achieve! But they still did it.
Horsepower is maximized, and the header and fit styles are universal. Which means you don’t have to worry much about this not fitting into your cars.
So rev up your engines, ladies, and gentlemen, because this queen is about to put you back on the road like a boss!
Well, there is not much to say about this product. It pretty much speaks for itself, considering that it has stayed in the market for so long, and is continuing to flourish, and making the lives of millions so much easier.
The cherry bomb red color is going to make you so proud when you look at it. The finished look is also very durable, so go for it.
The best part is that it is not meant for anyone type of audience, so this is like the one-size-fits-all type.
8. Thrush 24205 Glass Pack Muffler
Owners of pick up trucks! Beware and be ready! Because this one is meant specifically for my fellow truckers out there. But what is it that makes this product most suitable for the pickup trucks?
Some say it is due to the dual outlet mode that it features. Others say that the heavy gauge shell is what makes it so popular amongst the vehicle owners who are looking for a deep, pleasant rumble. What do we say? It is not just both of these that makes it such a likable product amongst amasses, but a lot more as well!
The dual outlet model allows it to be great for pick up trucks and customizable applications. The heavy gauge shell is what provides it with maximum durability and reliability. But, this is not it. We have got more coming.
The body is made up of stainless steel and painted on the outside to avoid rusting and corrosion. Bushings are expandable, means more customization!
Last, but not the least, the continuous roving fiberglass structure give it it’s signature power tone and, are also the secret to its long life. The straight design ensures maximum flow.
I’ve said it before, and I will say it again because I cannot emphasize this enough, that this product is particularly meant for my trucker brothers and sisters. You will be more than happy to buy this product.
And it is all because of the solid dual-outlet mode, which fits more than too smoothly in your truck.
So if you are a passionate trucker who is looking forward to giving their vehicle the parts that it is going to love, then this is the product for you!
9. AP Exhaust 351211S Glasspack Muffler
This product is going to last longer than the rest of the exhaust system. Color me impressed.
This piece is too compact, yet too long-lasting. This 2 Inch glass pack is going to muffle the high flow. It filters most of the noise.
If you combine this muffler with header and the exhaust pipes of the right size, you will get an unmatched and unbeatable performance. That is just a luxury, not a necessity.
Let’s talk about how it changes the sound of your vehicle. It tones the sound of your engine down and makes it not too much and not too quiet either.
So this is your pick if you want something moderate. It is fairly easy to install, which gives this part an upper hand.
The good thing is that there is no pain in the exterior to burn off. The 14 gauge steel is just amazingly stout. It will last long enough without that as well. It manages the job just fine and is worth the price.
You wouldn’t find anything better than this if you are willing to spend the amount of money you can buy this in.
If you want a brand that offers quality which closely resembles that of a cherry bomb product, then this is going to be your jam.
Moreover, it does that in a price range that is almost half as that of a cherry bomb. Means more features for less amount of money. I would buy that. I would buy the hell out of it.
10. Jones Exhaust A3518s5 Glasspack muffler
Finally, we are down to the last product of this list. We made this a part of this list because it doesn’t have the recognition it deserves. It is almost as good as many other products in this list but slips from the sight of many.
Anyway, let’s talk about what it is made out of. The body is built from all-welded aluminum, which gives it extraordinary strength. The inlet and outlet pipes are straight, thus minimizing resistance.
It gives your engine a good rumble when combined with the other parts. They will hear you coming! A great deal in a low budget. It will fit whichever vehicle you own, be it a car, bike, or a truck.
This product will give you the most pleasant sound when combined with the other parts of your engine. If you look for extreme strength, in a product that doesn’t even charge you like it should for it, then you must get this one.
And the good part is that it fits within almost any vehicle, provided that you make the necessary amendments.

Things to consider before buying a glass pack muffler
The first thing that you need to consider is the size. Even though the pipes are somewhat adjustable, still, the size of the muffler needs to be by your vehicle. It should be neither too big, not too small compared to your engine.
Too much of a difference is going to create problems. If it is too big, it won’t fit, and if it is too small, it will keep hitting against the walls.
The material of your muffler will determine its longevity. The more sturdy the material, the longer it will stay with you.
Moreover, you need to get a muffler made out of insulating material if you live in a warmer place, as you don’t want your muffler contributing to the overall heat of the engine. If you live in colder parts, however, you can get metallic mufflers as well.
Consider the kind of sound you want. If you want to muffle the sound as much as possible, you should get a longer muffler.
Longer mufflers tend to dampen sounds more, as they have more amount of fiberglass, which in turn means they can absorb more sound. Shorter ones absorb less sound and will be your only choice if you don’t have much space.
Next, to material, finishing is what will determine if your muffler is going to last or not. If you get one with clean, polished finishing, it will not rust and corrode easily over time.
However, there is no finishing on the product, it will corrode inside the engine, and the parts around it will also be affected. So if your muffler does not have a proper finishing, make sure to paint it before you make it a part of your engine.

Our curious mind paves the way for many questions. But we have your back here as well. Here, we have a list of questions that may pop up in your heads, and we have answered them all before you even ask!
• What is a glass pack muffler?
A glass pack is a kind of muffler. In the glass pack muffler, the exhaust gas passes through the middle of the muffler. The basic design is, there is a small tube that is placed inside a larger tube which is swollen in the middle.
So in the middle, there is a distance between the smaller tube and the larger tube, which is full of fiberglass. And that’s where it gets its name from.
• What purpose does the glass pack muffler serve?
Glass packs are aimed at reducing backpressure. However, they will not prove to be very effective when it comes to reducing noise.
A glass pack that is longer will be able to reduce sound more effectively than a shorter one. The sound also gets dissipated in the fiberglass that is present in between the tubes.
• Do I need a glass pack muffler?
Of course, you do, every engine needs one. It is very effective when it comes to reducing the backpressure in a vehicle. They also modify the sound of the engine. If you run without them, the sound of your engine will become unbearable, and driving will become impossible, especially on longer routes.
So you do need one, and they are also very cheap, from $20 to $100, so not very difficult to get either.
• What are glass pack mufflers made out of?
Every glass pack muffler has one material in common, and that is fiberglass. That is the reason why they are called “glass pack.” The material that the tubes are made out of may vary, though.
They could be made out of steel, aluminum, etc. In the end, it all depends on who you’re paying, and how much you are paying for it. The more you pay, the better the material.
• Do glass pack mufflers wear out with time?
They may get quieter with time, and you can always fix that by a simple process (refer to the FAQ, “how to make the glass muffler louder”).
Apart from this, the only thing that can happen to it is that it may corrode over time, but that can be avoided by getting a muffler that has a good finishing or painting the surface wit a good paint that doesn’t melt yourself.
• What is the best glass pack muffler?
There are just so many glass pack mufflers available in the market. The carefully picked, tested, and proven to be good are listed above with all their pros and cons.
• What are the advantages of glass pack mufflers?
- They are supposed to reduce back pressure on the engine
- They muffle the sound of the engine
- They make your vehicle more drivable
- Without them, the sound of the engine will rip your earbuds apart, especially during longer distances

• How do glass pack mufflers affect the sound of the engine?
They make the exhaust of the engine pass through a sleeve of gas, which means they muffle the sound of the exhaust. Also, the fiberglass absorbs the access sound waves, which means the sound does not get reflected the engine, which means less damage.
• How to make glass pack muffler louder?
The first step you need to do is to start your car and let the engine run for at least 30 minutes.
Then, stick a water hose right into the glass pack muffler. Turn the water on for not more than a second. If you let the water run for too long, it will give rise to corrosion inside the muffler, which is something that we don’t want.
Lastly, keep revving your engine after every few minutes pass for the next 30 minutes to make sure every single water vapor flushes out of the system. And there you have it, clean and louder sound without having to replace your muffler!
• How loud is a glass pack muffler?
The purpose of the muffler is to negate the loud sound of the engine by producing the same amount of sound itself.
However, a glass pack muffler is supposed to reduce the sound produced by the engine and thus reducing pressure. It does so by dissipating the sound wave pressure through some gas particles. So the sound it has depended upon its performance.
There you have it. A complete guide for a potential muffler owner. Keep a budget plan in mind, and buy a product that best suits your needs. We hope you manage to get the best glass pack muffler that is meant for you. Happy purchasing!
