You might be asking, is there such a thing like a quiet performance muffler? Well, in this guide, I’ll be reviewing some of the quietest high-performance mufflers you can get on the market today.
Mufflers play an important role in a car’s exhaust system. They are designed to reduce car noise. In most states, it’s a legal requirement to have car mufflers. (Source)
This helps in significantly reducing excessive or unusual noise and smoke. There’s more than meets the eye when it comes to choosing a muffler for your car. The muffler you choose will alter the way your car sounds; some will offer a deep growl while others will make your car as quiet as possible.
What Is a Performance Muffler?
Besides noise reduction, mufflers also affect vehicle performance.
This brings about the term performance muffler.
A performance muffler reduces exhaust restrictions such as baffles and reverse flow to help the engine breathe freely without compromising noise control.
Performance mufflers have a pretty good fine-tuning with a balance to boost performance while suppressing exhaust noise.
Also, they’re more expensive than stock mufflers but are more effective in reducing back pressure without making the exhaust louder. Besides, they increase your vehicle’s horsepower hence boosting its performance.
Straight through vs. chambered vs. Turbo: which one is the quietest?
Like I earlier stated, a muffler design will determine how quiet and how noisy the muffler is. Let’s have a look at the various design and how quiet or loud are.
As its name suggests, Glasspack mufflers are packed with sound-dampening materials such as steel wool or fiberglass, which are good sound deadening products.
They have a packing wrapped around a perforated pipe. The pipe-which is straight- allow gases to flow smoothly without being backed up hence giving maximum horsepower, which is great for racing.
Glasspack designs make the best performance mufflers. Unfortunately, they are often loud, which could be a disadvantage when you’re looking for a quiet muffler.
Unlike straight through, chambered mufflers create a deep sound which is quieter. They have a series of inner chamber that bounces sound waves around so that some waves end up canceling each other out.
It’s pretty easy to alter the sound produced by chambered mufflers by adjusting the shape and the size of the inner chambers. These are great for muscle and streetcars.
The turbo types combine the technology used in both chambered and Glasspack.
They work by channeling gasses through S-shaped tubes which have sound dampening materials applied around them.
While they have more pressure on the system than the two above, they make for a quieter running engine.
How does a quiet performance muffler work?
All mufflers are designed to alter the noise your car emits- typically making the car quieter. How a muffler will work depends on whether you choose chambered design or glass packed design, but both works to reduce the noise emitted in one way or another.
These mufflers utilized destructive interference (Source). As the sound waves travel through the component, they are forced to bounce through strategically placed chambers which direct them in such a way that some waves cancel each other out.
This means that only a few sound waves end up emitted from the exhaust system, and hence, the sound emitted is quieter.
The chambers and tubes inside chambered mufflers can be altered to alter the sound emitted.
These have the simplest design. They are packed with sound-deadening materials in most cases fiberglass, but at times, steel wool is used.

How To Quiet Exhaust Without Losing Performance
The exhaust system can be a little annoying by becoming loud suddenly. I have experience with that, and I can tell how annoying it becomes; you can’t even drive your car at peace.
Although, I want to share a simple guide that you can use to identify and solve the source of the loud noise in the car exhaust. By following the 4 steps below, you’ll quickly deal with that challenge;
Before we get to the steps, let’s go through the materials you need to handle this issue. The materials include;
- FiberFix Heat Wrap
- Parmatex Epoxy Stick
- Rust Penetrant
- Exhaust Sealant
- Luxury Liner Pro.
Now, it’s time to solve that exhaust loud noise problem.
Step 1. Find Out Where the Leak Is –
Place your car in an elevated position, jack it up from the rear exhaust side. Lie beneath, listening to where the sound is coming from. All this time, your car engine should be running. When you’ve found the leak, it’s time to fix it.
Step 2. Fix The Leak
If it’s a small leak, use the exhaust tape to fix it. However, if it’s a big leak, use a patch together with epoxy for sealing. Patch kits are available in any auto part store.
Ensure you clean the area before applying the material you’re using to seal. Some instances might call for a muffler change that takes us to the next step.
Step 3. Replace The Muffler
If the exhaust didn’t get back to normal sound after fixing, you might need to change the muffler.
Here, be extra keen when replacing the muffler; some models may not fit your car. So, you need your vehicles’ year of manufacture and model to get the exact muffler type.
A WD-40 will help you loosen the bolts; if your vehicle has muffler clamps, look for a wrench to loosen them. From there, separate the muffler from the exhaust, then clean the muffler resting area before fixing the new one.
Step 4. Make The Car Interior Quieter
If all the above steps fail, which I doubt, you can soundproof your vehicle from inside. This prevents you from hearing the loud car exhaust.
Use a sound deadener such as FatMat and put it in your car’s noise vulnerable areas. Note, sound deadener limits sound transmission through your car’s metal panels. It doesn’t prevent noise from the car’s floor.

How does a muffler reduce noise?
Mufflers use internal perforated tubes, also known as baffled chambers, to reduce noise. The chambers create opposing sound waves when the noise travels through them, thus canceling initial sound waves.
