How to Make Your Car Louder: 3 DIY Budget-Friendly Ways!

how to make your car louder
Written by Nick Steiner

There are times when you wish that your car was louder. Perhaps it gives you a thrill, you want to feel sporty, show off, alert your neighborhood of its presence, or bring slight improvement in its performance.  Well, we get it! and sometimes it’s hard to say No to a louder car.

How a Car Generates Sound

If you’re wondering how to make your car louder, first you need to understand how a car generates sound. Once you understand the process, you will be able to modify and enhance your car sound very easily.

A car generates power through combustions by mixing fuel and air in the combustion chamber. These combustions generate sound waves which travel through the exhaust system and then exit the car. When travelling through the exhaust system, the sound waves pass through resonators and mufflers whose job is to silence the sound waves.

If you need an engine with aggressive sound, you must remove and/or modify the parts (resonators, mufflers, and the exhaust pipes) silencing the sound.

How to Make Your Car Louder?

1. Small holes in the exhaust system ($10-15$)

Small holes in the exhaust system

If you are on a budget but still want to make your car louder, try this method. All you have to do is drill a few small holes in the exhaust pipe that’s right before the muffler. When the engine ignites, some of the sound waves will exit the exhaust pipe through these small holes before they’ll be silenced by the muffler.

In this way, a more aggressive and louder sound will be produced. However, it will still not be so loud as most of the sound waves will still travel through the muffler.

We recommend that you drill 4-6 holes with a 3/8 inch drill bit.

Where should you drill holes in the exhaust?

It is important to drill holes at the right place in order to avoid any unnecessary damage to your car. You should drill holes right before the muffler and after the catalytic converter. In case a hole is drilled before the catalytic converter, it will release toxic gases into the air or into the back of your car.

2. Remove the muffler ($25-$35)

Remove the muffler

This method involves the complete removal of the muffler from the exhaust system. To replace the muffler, a piece of pipe or pipes are welded to the exhaust pipe. When you cut-off the muffler, sound waves will exit the exhaust pipe without being silenced. In this way, the sound of your car will be more aggressive and significantly louder.

Before you remove the muffler, please make sure that it is legal in your state. Because some states urge that a car must have at least one sound silencing device.

3. Install a resonator exhaust tip ($40-$50)

Install a resonator exhaust tip

A resonator exhaust tip works the opposite as a sound suppressor/muffler. Unlike mufflers that bounce sound waves against the plates and silence them, Resonator Exhaust Tips make the sound waves vibrate in a way that makes them aggressive and sound louder.

It is very easy to install a Resonator Exhaust Tip. All you need to do is just clip it onto the tail of the exhaust system.

 Why install a resonator exhaust tip

Typically, if you do have a budget of $40-$50 and want to make your car louder, we recommend you to install a resonator exhaust tip since it is legal in almost every state, easy to install, affordable and makes your car look better with outside visibility.

A resonator exhaust tip will surely modify and enhance the sound of your car, making it considerably aggressive and louder. However, it won’t make the sound super louder as it is just a small device clipped onto the exhaust tail.

4. Install a performance muffler ($70 – $90)

Unlike a regular muffler, the performance muffler doesn’t suppress the sound waves but instead modifies them to sound more loudly. Performance mufflers in comparison with regular mufflers are more hollowed with fewer plates inside.

This enables the sound waves to go out of the exhaust system without being silenced much, making the sound of your car significantly louder. The hollowness of the performance muffler also allows easy exit of exhaust gases, resulting in enhanced sound and performance.

Why install a performance muffler?

If you want to enhance the sound of a car and need a safer option, we recommend you to install a performance muffler. A performance muffler improves your car’s sound and the overall performance (slightly though) without putting any negative impacts on the engine.

Please note that some of the performance mufflers are illegal in many states as they make your car so much louder. Therefore, before installing it, make sure it is legal in your state.

5. Get a cold air intake ($200-$250)

If you want a performance boost, the Cold Air Intake is a perfect option for you.

A cold air intake system (CAI) enables a car’s internal combustion engine to suck in relatively cooler air right below the engine inlet, near to the wheel. When the engine sucks in a greater amount of cold air, its performance is improved.

Cooler air contains abundant oxygen (O2) that ignites more easily and creates powerful combustion when mixed with fuel. A powerful combustion boosts the performance of a car and creates aggressive, deeper and louder sound.

Why install a cold air intake?

Try it only if you love the unique and super louder sound it produces. Additionally, you’ll enjoy a slight performance boost with enhanced horsepower (20-30), a unique sound as you push the accelerator, and a cool look added to the engine inlet.
