Unless you’re a showoff that is screaming for attention, having a noisy exhaust really drains the fun out of the driving experience. Unless you are driving a Lamborghini Diablo or a Dodge Charger Hellcat wherein the ear-splitting roar of the exhaust is a visceral part of it all, chances are you are like most people in the world (including myself) that don’t have one. Instead, you probably have something more pedestrian, but is up against an excessively loud exhaust.
Most cars now use quiet mufflers that substantially diminishes the sound that is coming out from your exhaust. However, if you possess a relatively old car that is perhaps 15 years or more years old, you may not have one.
This basically means that the sound coming from your exhaust will be way noisier and it will also mean that your exhaust may be more vulnerable to getting damaged by road wear like stones flying up and hitting it, or even rust. Both of these can actually lead to sound issues if they cause enough damage to create a hole in your exhaust pipe.
There is honestly nothing that’s more vexing than hearing a car with a loud exhaust going down your street. As a matter of fact, having an overly noisy exhaust is considered illegal in some places and offenders can get fined.
Fortunately, there are several ways that you can quiet your car exhaust. I’ll share some tips and tricks in this article on how you can make your car as quiet as possible, as well as recommend the best quiet mufflers in the market today. But before anything else, let me give you some vital information on what a muffler is and what it does for your vehicle.

How Muffler Works And Things To Know About Car’s Muffler
Let’s first discuss some of the basics involving a car muffler.
Now, a muffler is always attached to the mouth of the exhaustion pipe at the end. In the internal system, a muffler has many tubes or chambers that help to tune the noise and minimizing it. It is all about the sound waves where one sound wave plays opposite to another soundwave. And when these two sound waves add up, it results in zero or no noise. Meanwhile, here are some more important things that you should know about regarding mufflers.
Things You Should Know About A Muffler
1) It Gets Rusty
Whenever you buy a muffler, the issue of rust is never too far. Even if a muffler says it is rustproof, after a while, you will start noticing the rust which can be seen usually around the welds. The rust issue occurs because of the water that turns into steam if not burned completely. Weather conditions also have a huge effect on mufflers.
2) It Needs to be Replaced
If a muffler doesn’t cut the sound or noise, then it’s high time for you to consider changing your old muffler for a new one.
3) Single Or Dual Muffler?
As the name suggests, single muffler means one exhaustion path and dual means there is two of them. Most of the vehicles only need single muffler unless you have an atrocious noise that cannot be handled by just one muffler.
Now that we have discussed some of the basics involving a vehicle muffler, let’s turn our attention to the reasons why your car is so noisy.
Already aware what these reasons are and want to jump straight to my recommendations? Click here!
Why Is Your Car Exhaust So Loud?
The clear reason why your exhaust might be noisier than most is the exhaust itself. What that basically means is that your car could possibly be sounding off because your exhaust is either too powerful or just plain old.
Take a look at those sports cars that you often see on TV — those luxurious, limited edition whips that sound like Bruce Wayne just rolled up in his Batmobile.. The point is, they’re incredibly powerful, which also makes them incredibly loud.
However, some old cars have incredibly loud exhausts as well, which is due to rust. Often, you can even hear the pipes rattling against the bottom of the car as they come unfastened. And of course, these cars naturally have an assortment of other things loose inside them, although you can dash a lot of those with some well-placed sound dampening materials.
There is one more pretty weighty issue that might be the reason for your exhaust to act up: leaking.
How to Determine If Your Exhaust Pipes are Leaking
If your exhaust system was compromised, it may have holes somewhere along the way. The way to check if this is the case with your car is by parking it for a minute to see if there are puddles or smoke under the car. Just make sure that your car can’t slip back and harm you. Find a flat area to do this on, and use the breaks.
Go from front to the back of the car, keeping an eye out to see if any of the parts are leaking. If you hear any weird noises from your engine, it could be that there is in fact, something wrong with your valve lifters. However, if you do find that the problem is a leaking exhaust pipe, there’s a pretty easy way to fix it. Here’s what you should do if you find a hole in the exhaust.
1. Fix the Leak
You might think that repairing a hole on something that gets as toasty as an exhaust pipe would be really difficult, but the reality is that it’s really not. All it takes is the correct material. For this, you’ll want to get your hands on heat-resistant epoxy.
However, if you’re trying to take care of a larger hole, that epoxy stick might not prove sufficient. So you might want to something like this Dynomax muffler cement.
It goes without saying that you’ll need to meticulously clean any rust off of the spots you’re dealing with before application. However, if your whole exhaust is riddled with holes or rust, no amount of repair materials will work and you are going to be better off buying a new muffler.
2. DIY Soundproof Mufflers
The purpose of your car’s muffler is to lessen the noise created by the motor, like some kind of sound filter. If you want a quieter ride in your car but do not have the resources to purchase a quiet one, you may want to learn how to make a quiet muffler. If you are hearing more noise than usual, then you’ll want to make your muffler softer. Not only will your ride be more peaceful, but your passengers will also feel at ease as well.
Items you will need
- Muffler Silencer
- Glass packing kit
- New muffler
Consult your car owner’s manual to check what type of gas your car requires. Many upper-scale cars need high-octane gas. If your car needs high-octane gas and you’re filling it with regular gas, then your muffler will definitely make noise. If this is the situation that you are up against, merely switching to the right kind of fuel your car needs will instantly fix your muffler noise problem.
Put in an exhaust muffler silencer. Silencers are designed to be used in tandem with the muffler your car already possesses and will reduce sound levels without any losing any power. All silencers are fitted differently, so follow the precise instructions that are in the manual that comes with the silencer.
Try to use glass packing. You can wrap your muffler in a pack that is made up of a special metal tube lined with glass. The tube is wrapped in steel to keep it from breaking. You can put in a glass packing tube easily. Check with the manufacturer of the model you bought for precise installation instructions. You can buy these packs at any auto supply shop.
Check that your exhaust system is operating appropriately. A well-functioning exhaust system should function noise-free and efficiently. Pay attention for any loud noise, dinging sounds, and vibrations. No thick smoke should be seen coming out of the exhaust when your car is moving. If your car starts making noise, you might need to switch up the muffler or its pipe. Take your car to a professional mechanic for an inspection to see if there’s a problem with your muffler or some other part of the exhaust system.
3. Purchase a New Muffler
If you can hear your exhaust while you’re driving down the road, you can be sure that people outside of the car are bearing the worst of it. Still, most cars have a solution for this. One crucial part of the exhaust system is the muffler, the part that envelops the last part of the pipe before the opening. The muffler’s main function is to make the exhaust softer, and if it’s failing at that duty, it may be time to purchase a new one. And so, without further ado, here are the best quiet mufflers that you should consider picking up.
