How to Keep Your Truck Muffler Quiet

If you own a car, it probably has an exhaust pipe. If you own a truck, it likely has one too. And if yours is anything like mine, the sound of your truck’s muffler can drive you absolutely batty. You start to feel like you’re losing your mind, because that noise won’t stop!

But here’s the good news: there are quite a few things to try before giving up completely and shelling out for an expensive replacement. That’s where this guide comes in handy.

In this guide, we’ll talk about what a muffler is and why it makes noise, then we’ll cover a few quick tips for fixing your muffler. Let’s get started!

What Is a Muffler?

A muffler is a device that reduces the sound of an engine. It’s an important part of your vehicle, because it prevents you from annoying people at stop lights.

Most cars have mufflers built into their exhaust pipes, so people can hear the engine, but not much more than that. Trucks, however, are commonly equipped with mufflers that hang underneath their vehicles. These are much larger than car mufflers and they’re designed to handle the extra power of a truck’s engine.

Muffler Noise

If there’s no muffler, your engine sounds like an angry dragon. It’s loud, it’s raspy, and even if you turn the radio volume up all the way it can still be annoying. It can also emit strange noises that you never heard before. Perhaps the most common of these is a strange “tappity tappity tappety tappity” sound. It can be very annoying when you’re trying to sleep or it may distract you while you’re driving.

There is a lot of buzz and chatter and rattling and buzzing in the pickup truck world about how to keep your engine quiet. But in all seriousness, I don’t think these rumors are true! Truck engines usually don’t need mufflers, and if they do, they probably don’t need them as much as people think.

What is the quietest truck muffler?

Now, I will say that some trucks don’t need a muffler at all. For example, my truck (a GMC Sierra) doesn’t have one and it sounds great. It’s loud when you want it but quiet when you need it to be. Most people never notice it unless you point out the lack of a muffler… but even then, they’re like “Well, it looks like it should have one.”

I don’t know why mine doesn’t have one; I don’t think it ever did! But for other vehicles, you may need to just roll with the punches and accept that your car will be loud. You might be able to solve major problems by simply replacing your muffler with a better one.

How can I make my truck exhaust quieter?

If you truly do want to quiet down your truck, there are a few options. You can talk to your muffler shop about their mufflers, but you’ll probably find that replacing it with one of the same size is all they can do.

Instead, I have tried a series of tried-and-true solutions that are easy to try yourself. Even better, many of these don’t require you to go too far out of your way or spend too much money. Even if one of these solutions solves your problem, I’d recommend trying a few and seeing if any of them work.

What can you put in a muffler to make it quieter?

The cheapest way to fix a muffler is to poke some holes in it. Seriously, I’m not kidding. This tip comes from a mechanic buddy of mine, and it sounds absolutely silly. But he swears by this method!

Unfortunately, I don’t have any pictures of my truck’s muffler because it’s hanging underneath the car. But if you can take a look at yours, you’ll probably see that it consists of a series of chambers. These chambers are there to help reduce the sound and pressure of the exhaust.

But here’s the thing: If your muffler is making too much noise, then you probably want it to be more rigid. And guess what makes something more rigid? More pressure and heat! That means your muffler needs some holes!

So get yourself some big drill bits and start poking holes in the chambers.

Who makes the quietest muffler?

This is one of the few times I’ve actually used an ultra-niche search engine to find information. I just typed in “best muffler” and was amazed at how much there was! But after clicking through to find out more, I found that it’s somewhat hard to find reputable information about mufflers.

There are so many different types of mufflers on the market, each with unique designs. Some of them are “quiet” because they have a very simiplistic design, which makes it easy to remove some material from the inside. Others are designed in mind with a specific vehicle in mind.

There’s a reason that different mufflers are made for different vehicles: they all have different exhaust pipes and different piping designs. The only thing that matters when you’re shopping for a muffler is whether or not it will fit on your vehicle.

In fact, if you google “best muffler” you’ll probably get a few pages of similar questions from people who think they have a problem with their muffler. But do you really? I bet they don’t.

Which truck mufflers are quiet?

I’m going to give you the best muffler tip I have: don’t worry about it. Simply put, if you want your truck to be quiet, replace the muffler with a different model. That’s it.

Instead of worrying about what makes a muffler work and how to make it quiet, just look for one that will fit on your vehicle. I’m sure your muffler guy will have a few suggestions, and you can just go from there.

And did I mention that you should just replace your muffler? I don’t think it’s necessary to try and modify the one that you already have!

What does a loud muffler sound like?

Me, showing off my sweet flaming guitar solo skills. Seriously though, this is the kind of obnoxious noise that an obnoxiously loud engine makes. It’s kinda like a loud vacuum cleaner, and it’s something that you don’t want to hear every time you hit the gas. If your engine sounds like this, you probably need to either replace your muffler or get it repaired.

Can you do a burnout without a muffler?

Short answer: Yes. But…

Long answer: Yeeeeaaaah, I mean, it depends. No, seriously! Let me explain:

If you’re fully equipped with a thick coat of engine oil and you’re on a gravel road in a Barbie Jeep, then maybe. If you’re trying to do a burnout with a stock car and no helmet in a city-run parking lot… Maybe not. You can do it if you want, but let me tell you the things that could potentially happen:

Your engine will overheat and your car might catch on fire. When your engine is hot, it doesn’t take much for the oil to evaporate and it to burn! I mean, do you really want to put yourself in a position where your car could start on fire? I know I don’t.

Your tires will be ruined. Seriously, trying to do a burnout on asphalt will ruin your tires. And if the guy next to you doesn’t like you, he might key your car. Or worse!

You’ll upset people. Hey, give it a try if you want. But if you’re in a parking lot, you’re surrounded by other people who are likely not pulling the same stunts that you are. If you do it, they’ll hate you. And then they’ll post it on YouTube.
