1 Flowmaster 817633 Outlaw Muffler Kit – Best Loud Muffler

It has been said that the best muffler for dodge ram 1500 trucks is produced by Flowmaster. Their model number 817633 is an Outlaw Muffler Kit specifically designed for those with a classic body Dodge RAM.

If you want to catch people’s attention, this is the muffler for you…

Yes, there are some mufflers out there that will help minimize the noise produced when you accelerate. These are considered neighborhood-friendly mufflers, and they are quite popular. However, that’s not what we’re talking about here.

The Outlaw Muffler Kit is not designed to be neighborhood-friendly. This is designed to announce your presence so everyone around can get out of your way. We like the way this muffler makes your 5.7L Hemi rumble. You’ll both hear and feel it inside and outside the vehicle.

They say it’s not for the faint of heart…

And we agree. However, it is easy to install, which is a real plus. All the parts you’ll need and the instructions are included. Overall, we think the bolt-on stainless steel system does a great job of delivering both superior sound and performance. We also quite like that it’s made in America.

The Outlaw Muffler Technology used to increase the performance of your ride is race proven. Add on the dyno tuning the muffler undergoes during production, and you end up with a noticeable performance increase.

But is it too loud?

Well, for some, yes, it certainly will be. Some drives have noted that you never really get a break from the noise, especially on the highway. However, if you want your Hemi to sound as badass as a WWII tank, this is your muffler. We also advise that you check the supplied mounting clamps.

While the muffler is awesome, the other hardware supplied in the kit may not be top of the line. It’s an easy fix and one some drivers will want to make.


Flowmaster 817633 Outlaw Muffler Kit

Our rating:4.7 out of 5 stars (4.7 / 5)

Pros

  • Stainless steel construction.
  • Dyno-Tuned for increased performance.
  • Deep aggressive sound.
  • Outlaw Muffler Technology.
  • Made in the U.S.A.
  • Welded baffle-type muffler.

Cons

  • May be too loud for some drivers.
  • The mounting clamps are known to be problematic.

2 DynoMax 39510 Axle-Back System – Best Quiet Muffler

We love the aggressive rumble of the option we just reviewed, but do realize some will prefer to minimize noise. After all, many of us spend multiple hours a week in our vehicle. That’s why DynoMax makes their Axle-Back System, or model #39510.

Are you looking for an affordable performance muffler?

If so, this just might be exactly what you’re looking for. Designed with Super Turbo patented flow director exhaust channels, this muffler sets the bar. Not only do the large internal flow tubes minimize noise, but they also eliminate turbulence.

This is achieved by improving exhaust flow while simultaneously reducing backpressure. In the end, this means it is one of the best performance mufflers on the market and at a great price point.

But that’s not all…

In these mufflers, DynoMax also employs Fiberglass Matting Technology. This cuts down on undesired interior resonance, meaning a quieter ride. We think many drivers will appreciate this.

We also really like the Limited Lifetime Warranty and the ease of installation. This is thanks to a simple bolt-on design that allows most to accomplish a DIY job.

There might be a catch, though…

While we have not seen any issues first hand, there are reports of long-term issues. It seems that rust tends to be an issue on this model. This may be down to defects or perhaps even aggressive driving on rough roads. Regardless of any minor complaints, we think this is one of the best high performance mufflers for the price.


DynoMax 39510 Axle-Back System

Our rating:4.3 out of 5 stars (4.3 / 5)

Pros

  • Improves exhaust flow.
  • Exclusive patented Flow Director Design.
  • Fiberglass Matting Technology.
  • Flow proved up to 700 SCFM.
  • Backed by a Limited Lifetime Warranty.

Cons

  • Known to rust over time.

3 Vibrant 1141 2.5” Ultra Quiet Resonator – Best Budget Muffler

Next, in our reviews of the Best Mufflers, we have an excellent muffler for under $100 is made by Vibrant. We really like model #1141, which is better sold as the Ultra Quiet Resonator.

What makes this muffler so good?

Vibrant has designed this system to dampen the sounds coming from your exhaust. This is achieved without interrupting the exhaust flow. The unit is composed of T304 stainless steel, which means it won’t easily rust away on you. This is a big concern as the muffler often takes a beating from water and debris kicked up from the road.

There’s another benefit to stainless steel…

This muffler is also capable of handling high temperatures coming out of the engine. Even with the ‘true straight through’ design that’s optimal for performance, there is a noticeable reduction in rifling noise. And it’s backed by a 5-year limited warranty. We think this makes it one of the best affordable mufflers you can buy.


Vibrant 1141 2.5” Ultra Quiet Resonator

Our rating:4.8 out of 5 stars (4.8 / 5)

Pros

  • Reduced exhaust noise.
  • Constructed from T304 stainless steel.
  • True Straight Through perforated core.
  • Backed by a 5-year limited warranty.

Cons

  • Not the easiest to install.

4 MagnaFlow Exhaust Products 10416 Performance Exhaust – Best Muffler for All Vehicles

When it comes to doing things right, we think MagnaFlow Exhaust Products is on to something. Here we are looking at their model #10416 Performance Exhaust. It’s on our list for one very obvious reason.

What vehicle do you drive?

No, wait. It doesn’t matter. And that’s one of the best things about this muffler. MagnaFlow has designed a universal muffler that will fit just about any configuration. No matter your needs, no matter your requirements. MagnaFlow has just about every application covered.

That means that anyone and everyone can improve the performance of their ride with the best universal fit muffler. Plus, the price point is low enough not to deter most of us from going for it.

But does it look good?

Surprisingly to some, MagnaFlow has gone out of its way to design a beautiful muffler. Yes, it goes under the vehicle and is rarely visible. Still, people will get peaks of it as you fly by.

But the best part is how MagnaFlow lets you hear soundbites of what your ride will sound like with various mufflers attached. We think this is a cool feature, and it should ensure most buyers are very happy with their choice.

Now there is a downside…
Some drivers have noted that their fuel consumption increases with the #10416 installed. This is common for most high-performance mufflers, though most drivers may be unaware of such a fact.

While the muffler may increase your ride’s performance, it does so by allowing for greater airflow. This, in turn, means the engine will be able to pull the fuel through more quickly, so more trips to the pump.


MagnaFlow Exhaust Products 10416 Performance Exhaust

Our rating:4.6 out of 5 stars (4.6 / 5)

Pros

  • Universal exhaust design.
  • Looks good.
  • Sound clips available online.
  • Improves performance.

Cons

  • Professional installation required.
  • Aggressively increases fuel consumption.

5 Walker 18558 SoundFX Muffler – Most Durable Muffler

One of the best value mufflers for the price is the SoundFX Muffler line from Walker. Here we are looking specifically at model #18558. We expect many drives will decide this is the best muffler for the dollar.

What makes it so good?

Besides being priced very aggressively, this muffler provides a universal fit. That means that it’s bound to fit your vehicle, no matter what you may drive.

Now, this does not mean it’s a one-size-fits-all. You still need to ensure that you order the correct size for your car or truck. But, they are bound to have one available that’s designed for your undercarriage.

What is it made from?

Walker has constructed their SoundFX line from 100% aluminized steel. This provides a longer service life than other low-carbon steel options. We think this is important, considering the abuse your muffler receives. We also appreciate the mechanical interior joints and spun-locked heads. These features provide greater stability and durability on the road.

And lastly, many drivers have noted that the sound produced is perfect. It’s almost exactly in line with the sound given off by most OEM mufflers.


Walker 18558 SoundFX Muffler

Our rating:4.5 out of 5 stars (4.5 / 5)

Pros

  • Aluminized steel construction.
  • Tube-and-partition style design.
  • Spun-locked heads.
  • Mechanical interior joints.
  • Spot welded bushings.

Cons

  • May not provide that upgraded muffler sound.

6 DynoMax Super Turbo 17748 Exhaust Muffler – Best Value for the Money Muffler

Another great option from DynoMax is the model #17748 Super Turbo Exhaust Muffler. We think this muffler is one of the best for those on a budget. You’ll want the upgrade for a couple of reasons.

Precision matters in mufflers…

To keep things as quiet as possible, DynoMax has employed exclusive Flow Director Technology. The exhaust is channeled down through the muffler for less turbulence than in an open exhaust.

In fact, this muffler is proven to flow at 550 SCFM, which is rather astounding for the price range. This is in part down to the larger flow tubes. These cut on backpressure while also aiding the exhaust flow. Put this all together, and you end up with a quiet but powerful muffler upgrade.

But that’s not all…

To up things even further, this muffler also features fiberglass matting to help absorb resonance within the exhaust. What this does, is mellow out the tone of the exhaust. Even better, the unit is composed of the same aluminized steel as the other DynoMax mufflers reviewed above.

There is also an internal drainage system that helpfully cuts the moisture collection that leads to rust issues. All in all, we find it to be one of the best car and truck mufflers.

But we should also note the downsides…

And we would if we could come up with any. The universal fitment does have some fine print that some vehicles may require specialized installation.

However, it is available in a variety of body diameters, as well as inlet/outlet configurations. So, it’s likely that most people will find the installation fairly straightforward.


DynoMax Super Turbo 17748 Exhaust Muffler

Our rating:4.4 out of 5 stars (4.4 / 5)

Pros

  • Improves exhaust flow.
  • Internal drainage system.
  • Exclusive patented Flow Director Technology.
  • Fiberglass Matting Technology.
  • Flow proved up to 550 SCFM.

Cons

  • May require specialized installation.

7 Thrush Welded 17651 Exhaust Muffler – Best Muffler for V8 Engines

Next up, another producer of the Best Mufflers is Thrush, and we quite like their model #17651. This is their Welded Exhaust Muffler, and it’s a great option for most drivers for a couple of reasons.

Especially for those of you looking for a more aggressive-sounding muffler…

Yes, that’s right, we have another option that sounds like a badass ride from the Fast & Furious franchise. This unit is a twin-chamber muffler, which means it gives off a deeper and meaner sound. The result is one of the best sounding mufflers on the market.

But it’s not all show, as you will also see increased performance. This is thanks to the directional chambered design. It features flow director technology that provides a non-reversible flow.

But will it fit your ride?

Well, most likely, it will. But again, some customization may be required. The unit is available in a variety of fitments and sizes, so be careful to check all details before ordering.

One other point we quite like about this option is the sleek painted silver finish. The Thrush logo is embossed over this in an eye-catching way without being obnoxious. Add this to the 100% welded aluminized steel, and you end up with one of the best durable mufflers for the price.

However…

The only downside is that it doesn’t compensate for your truck’s shortcomings. If you have a nice V8 truck, this two-chamber exhaust will make your truck sound badass. However, some drivers have noted that V4 mini pickup trucks don’t achieve the same satisfying sound.


Thrush Welded 17651 Exhaust Muffler

Our rating:4.6 out of 5 stars (4.6 / 5)

Pros

  • 100% welded aluminized steel construction.
  • Embossed Thrush logo on a painted silver finish.
  • Chambered directional flow design.
  • Provides a deep aggressive sound.

Cons

  • May not provide the best sound on smaller engines.

8 Walker 18138 Tru-Fit Universal Muffler – Best Replacement Muffler

Sometimes you just need to replace your muffler. And if you’re not looking to supercharge things and just need a new muffler, Walker has you covered. This time we are looking at the Tru-Fit Universal Muffler, or model #18138.

Why choose this option?

We recommend this unit to anyone looking for something similar to their OEM muffler. At least in terms of the sound produced, this unit is one of the most similar to factory stock mufflers.

It features louvered tubes that cut on radiated noise. When compared to straight, perforated tubes, this design from Walker is much more factory-like.

Will it last?

Mufflers take a beating, and that’s why Walker builds these tough. They are constructed from aluminized steel, and corrosion is kept to a minimum thanks to the internal drainage system.

On top of all this, the tubes are mechanically joined to allow contraction and expansion. This is vital as the muffler is known to heat up extensively. The constant heating/cooling can cause expansion issues if it weren’t for this and the internal partitions.

But wait, there’s more…

To help ensure your muffler will last, Walker takes things one step further. OE-style spot welds and spun-locked heads provide longevity through stability. We think this is one of the best cheap mufflers available.


Walker 18138 Tru-Fit Universal Muffler

Our rating:4.5 out of 5 stars (4.5 / 5)

Pros

  • Very cost-effective option.
  • Mechanically joined tubes.
  • Aluminized steel construction.
  • Expandable busing for easy installation.

Cons

  • Doesn’t make your ride sound any cooler.

9 Thrush Turbo 17715 Exhaust Muffler – Best Classic Car Sounding Muffler

Thrush also makes a Turbo Exhaust Muffler design with their model #17715. This unit is a great option for drivers looking for that classic car sound.

So, what makes it worth the price?

Well, for one thing, these can be found for some shockingly low dollar signs. Despite being very reasonably priced, the Turbo series is made with a 100% aluminized-coated shell.

This matches up with spun lock heads to keep things durable and dependable. To make things even more desirable, this muffler features a Tri-flow design.

If you like that classic Thrush sound, this is the muffler you’re after…

Not only does it sound good, but it also provides the option for custom installations. If you’re looking to achieve a reversible flow, then this is your beast. It’s available in a wide variety of sizes and styles under the umbrella of the universal fitment label.

Now, some welding or specialized fabrication may be required for installation. Yes, this is a fairly common warning. It’s also a good reminder to check your make/model details before ordering any new automotive parts.


Thrush Turbo 17715 Exhaust Muffler

Our rating:4.5 out of 5 stars (4.5 / 5)

Pros

  • Delivers that classic Thrush sound.
  • Durable spun lock heads.
  • Aluminized-coated shell.
  • Universal fitment.

Cons

  • May require professional installation.

10 Walker 17911 Economy Pro-Fit Universal Muffler – Best Muffler for Cars

We’ll wrap up our list of awesome mufflers for cars, trucks, and SUVs with one final option from Walker. This time we have the details for their model #17911.

Why pic the Economy Pro-Fit Universal Muffler?

Well, there are a few reasons, and they’re pretty much all in the name. First off, this unit is priced for those on a budget. We know that sometimes you just need to unexpectedly replace a muffler.

Now, you don’t want to spend more than you must. But then again, you also don’t want to be at the mechanic doing it all again too soon.

That’s where the Pro-Fit Economy comes in…

This muffler is constructed from aluminized steel for durability and longevity in the face of corrosion. The internal workings are of the tube-and-partition style design. The bushings are spot welded, and we think that’s a good move. Overall, we find the unit to be stable.

There isn’t a whole lot to this option, but then that is part of the appeal. Especially if you have a compact hatchback like a Honda Jazz, this is one of the best small vehicle mufflers out there.

Varying difficulties with installation…

As we’ve noted, this unit may require some customization to install. It will depend on the make/model of your vehicle, and some will find it a very simple DIY job.


Walker 17911 Economy Pro-Fit Universal Muffler

Our rating:4.5 out of 5 stars (4.5 / 5)

Pros

  • Aluminized steel construction.
  • Spot welded bushings.
  • Priced aggressively.
  • Easy to install.

Cons

  • Not ideal for larger vehicles.

Best Mufflers Buying Guide

Best Mufflers Review

Now that we have shown you some of the best quality mufflers available, it’s time to discuss narrowing them down. Every item in our review is going to be the best muffler for someone. However, that doesn’t mean that they all are created equal.

When looking for a new muffler, here are the things to consider…

Exhaust configuration may seem like an obvious starting point, and that’s because it is. It’s also the most logical, as not all mufflers will fit all automobiles.

The first thing to verify is if you have a single or a dual exhaust coming out the backend of your ride. The next thing to do is verify that you have the required space in the undercarriage.

Emissions testing can get you in trouble with a new muffler…

This is down to the fact that not all mufflers are street legal. Smog test requirements vary depending on local regulations, and your vehicle will need to pass for the registration renewal.

For this reason, we highly recommend sticking with mufflers that are rated as street legal. It’d be a shame to update your wheels with a new muffler only not to be able to drive it.

Now for the real reason to upgrade your muffler…

When it comes right down to it, most of us swap out the muffler for one of two reasons. Either you’re looking for increased performance or to alter the sound produced when you put your foot down.

Finding the best muffler for your car or truck is down to balancing three things. The sound produced, fuel economy, and available horsepower. So, let’s address each of these in turn.

It’s all about the noise…

It doesn’t matter if you’re looking to decrease resonance for a quieter ride or tune it up to announce your presence. Replacing the muffler on your car or truck can drastically alter how it sounds.

You can choose a roaring ‘here I come, get out of the way’, or a high-pitched ‘bet you can’t catch me’ tone. Or, you can choose a muffler that cuts the tone to almost electric car levels. It’s all a matter of personal choice, but it all starts with swapping out your muffler.

The muffler can also significantly alter your vehicle’s horsepower…

Best Mufflers Buying Guide

If you’re looking to increase your ride’s performance swapping out the muffler is again a great place to start. High-end mufflers will often allow increased airflow while simultaneously decreasing back pressure on the engine.

This, in turn, provides more available power, as well as a higher throttle sensitivity. Many drivers looking for a bit more of a boost from their ride often upgrade the muffler for this reason.

Mufflers can also affect the gas mileage of your vehicle…

This aspect can go both ways in terms of fuel economy. Most mufflers on the market are designed to increase fuel efficiency. These are great options for upgrading your car or truck, as they often pay for themselves in savings at the pump.

However, it’s worth noting that some mufflers will actually increase your fuel consumption. That deep aggressive sound many of us want from our trucks comes with a hidden cost. Not a huge one, but it can add up if you do a lot of driving.

The final consideration is the price, but don’t be fooled…

It is completely and totally possible to find a new muffler replacement for next to nothing. The question is, how long will it last before you need to replace it again?

Mufflers can be made from a range of materials, but we strongly suggest choosing one that’s corrosion-resistant. The muffler takes a beating from road spray, ground salt, and the rest.

Plus, when holes rust into the muffler, you completely negate any performance or sound improvements. So, spend a bit more and get a muffler that will stand up to the harshness of the road.

What are the Best Mufflers?

As you can no doubt tell, there are several great options in the running for the best muffler. Which one is the best for your truck, SUV, car, etc., is down to a few personal preferences. Hopefully, we have helped you find exactly what you need.

But, if you still not sure, we’d recommend the…

DynoMax Super Turbo 17748 Exhaust Muffler

It’s built well, designed to fit almost any vehicle, and priced rather aggressively. In addition to all of that, this muffler provides a delightfully minimal sound from your ride’s backend.

So until next time, may the road treat you right.
