How Do You Make A Car Louder – Exhaust noise – for some it’s music and for others it’s noise. It’s hard to rationalize why most of us car enthusiasts love loud exhausts. But there’s no denying that there’s something incredibly satisfying about changing the sound of your car.
It needs to be done right. “Car mods” such as drilling a hole in your exhaust or installing an oversized muffler (fart can) will make your exhaust louder, but won’t help performance and won’t sound good.
How Do You Make A Car Louder
You want to keep things as functional as possible or at least avoid crashing. The whole point of modifying your car is to make it better than before.
Why Do People Like Loud Cars?
With this in mind, in this guide, we will cover the 10 most effective and proper ways to make your car exhaust louder and better sounding.
Exhaust sound and engine sound are two different things. No matter what you do with your exhaust system, there is no way you can make your inline-4 engine sound like a V8, or your boxer engine sound like an inline-6.
There are many factors that shape and influence exhaust health. When you listen to the car spin, all you hear is a combination of sounds coming from the engine, intake and exhaust system.
Automakers devote large budgets to their NVH (noise, volume and loudness) department to develop the ideal exhaust sound.

The slightest change in your exhaust system can change your exhaust tone, but only to a certain extent.
Knowing how the exhaust system works will help you understand a lot about why a car’s exhaust sounds the way it does.
Understanding what makes your car sound like it will help you choose the right method to make the exhaust sound different or louder.
There are many different ways to do this – the upgrades start at nearly $100 and work their way up into the thousands.
Test pipes and exhaust cutouts are inexpensive upgrades that allow you to modify the sound of your exhaust on a budget.
But if budget is not a concern and you want to see a real increase in performance, we recommend installing an exhaust system or cutback headers – this will make the biggest difference.
This modification is centered around the idea of improving your exhaust tone. You won’t see a measurable increase in power but your car will get a little louder.
If sound is all you want and you don’t really care about going faster, the following exhaust mods are your best bet.
Why Quiet Cars Are Getting Louder
Ever wished you could switch between louder and softer exhaust tones with the push of a button – loud when no one is around, and soft when you don’t want to attract attention?
The exhaust circuit breaker allows you to do this. It can be installed anywhere along the exhaust pipe connecting the center pipe with the muffler.
The device is engineered to temporarily open an air vent to allow exhaust gases to escape. Because this vent is located behind the exhaust, it makes the exhaust sound higher when open.
The vent opening and closing mechanism is handled by a butterfly valve – as you can see on the throttle body. This valve is mechanically operated by a vacuum hose connected to the engine.

The vacuum hose is turned on or off with the help of a solenoid connected to a wireless receiver.
Ergo, when you press a button on the included remote key fob, it opens and closes the exhaust port.
Whether exhaust tips make your car louder or not is a hotly debated topic. We found that they slightly changed the degree of the exhaust, but they did not make it any louder.
Because they are mounted at the end of the exhaust system, it is almost impossible for them to impact air flow. An added advantage is that they add to the aesthetics of your car.

Then you should definitely consider installing a rear axle exhaust system. Although not as cheap as exhaust tips, they are much better buy.
The rear axle exhaust was meant to replace the stock exhaust tip and muffler. They don’t add any power but they are the lowest hanging fruit when it comes to making your car sound a lot nicer.
Glasspack exhausts are similar to aftermarket exhausts in terms of performance, but differ in the way they are constructed and the materials they are made from.
It is basically straight hollow pipe wrapped in fiberglass packing. It is compact, flows very well, and in some cases even helps reduce back pressure and improves scavenging.
Do Loud Pipes Really Save Lives?
However, installing one of these will require you to cut the exhaust pipe. The result is a louder rumble and slightly quicker throttle response.
This is the real deal – the mod you absolutely want if you want to make your car sound better
There is nothing better than a car that goes as fast as it sounds. If you want to see some real performance improvements and improve the sound of your exhaust at the same time, consider taking a look at these exhaust mods.
Straight pipes are the holy grail of exhaust mods, but they are ready for track use due to the added performance boost and annoying loud sound. Depending on where you live, they may also make your car illegal to drive on the street.

This is because straight pipes replace your car’s catalytic converter, allowing for much better exhaust flow and a much louder sound.
Cat-con is the most important flow restriction in your exhaust system. Removing them frees airflow and helps performance.
However, if you will be driving on the road 90% of the time and hardly ever take your car to the track, we recommend keeping your cat-can intact.
Resonators are usually installed just before the exhaust and are responsible for shaping and shaping the exhaust frequency, before it actually gets to the exhaust.

Think of the resonator as a pre-muffler. Without it, your car would sound, er, interesting. The exhaust must work with the raw health of the engine and will not be able to do its job well.
This is what will make your car louder. We don’t really see the point in removing the resonator and keeping the stock exhaust anyway.
Once you start removing components from your exhaust system, you will find that you should just go all out and keep it as clean and straight as possible.
The point of a muffler is to close the sound of the exhaust, making it quieter and more reliable for uninitiated non-car people and governments.
Effects Of Having A Hole In Your Muffler
By removing them entirely, you will be bypassing the main components that make your exhaust sound and your car will definitely be louder. However, we do not recommend that everyone perform muffler removal. You need a muffler – the right kind.
These are usually included with aftermarket cutback exhaust systems. They are lighter, less tight and more free-flowing than regular mufflers. Or you can go ahead and install a glasspack muffler.
Aftermarket cutback exists strike the perfect balance between affordability, power gain and louder sound. If you have to pick just one product from this list to make your exhaust louder, make sure it’s this one.
Cutback exhaust replaces everything behind your catalytic converter with straighter pipes with fewer restrictions. It is designed to replace your factory exhaust system with a better flowing one.
Common Reasons For A Loud Exhaust
No matter what car you drive, as long as it’s in the aftermarket community, you’re likely to find a cutback exhaust for it.
The exhaust manifold was the first set of exhaust pipes to be bolted directly to the engine. When the expelled gases leave the cylinder for the first time, they accumulate in the collector manifold and are then released into the rest of the exhaust system.
The header and exhaust manifold are basically the same thing. It’s just that aftermarket exhaust manifolds are referred to as “headers”.
For more clarity on the difference between headers and exhaust manifolds, or the differences between 4-2-1 and 4-1 headers, see our article on the subject.

When it comes to invasive exhaust upgrades, the headers are up there with straight pipes. Considering that the manifold has the most important function in the exhaust unit, modifying it will make a big difference to the health of your car.
By replacing your factory manifold with an aftermarket header, your car will sound like it is on the track.
The Y-pipe is generally used on cars with a 6- or 8-cylinder V configuration engine that requires only one exhaust pipe. Its function is to collect the exhaust gases from the left and right edges of the exhaust manifold.
The idea is to incorporate the gas at the point where most of the power can be extracted. If your car has a V6 or V8 engine with a single exhaust, your exhaust system will most likely have an OEM Y-pipe.
Signs And Symptoms Of A Bad Muffler
By upgrading your stock Y-pipe to an aftermarket one, you can relieve many of the limitations in your exhaust system, making it louder and significantly lighter.
