How to Make My Motorcycle Exhaust Louder – 4 Ways


Motorcycle exhausts generate a deep and unique sound. You may want to amplify this so that you can customize your riding experience or to simply turn heads as you ride down the street.

There are numerous ways by which you can make your motorcycle exhaust louder. You can get an aftermarket exhaust, modify your stock carburetor, customize your muffler, or change the ignition. These modifications can be done on your own or by bringing in your motorcycle to a shop.

These tweaks can drastically change the sound of your motorcycle by making the sound louder or deeper.

How To Make My Motorcycle Exhaust Louder

1. Get An Aftermarket Exhaust

Installing aftermarket exhausts is one of the easiest ways to amplify the sound of your exhaust. This allows your motorcycle to free up more power and therefore, improve the way the engine runs. The faster rate by which heat and other by-products of combustion exit the motorcycle is due to the larger opening. That means that your motorcycle can somehow breathe better. This also increased the volume of your exhaust.

2. Modify Your Stock Carburetor

Your stock carburetor will likewise influence the sound of the motorcycle exhaust. This part controls the ratio of the air and fuel that enters the chamber for combustion. A larger carburetor will allow more quantities to enter the cylinder so it often leads to a stronger power as well as a louder noise in your exhaust.

Bigger is not automatically better. Make sure to compute for the carburetor cubic feet per minute to arrive at a volumetric efficiency of about 80%. That will be your range.

3. Customize Your Muffler

The motorcycle muffler is also known as the silencer. As the name implies, it cushions the outburst of heat and gases so as to minimize the noise of your engine. One option to make your exhaust louder is by removing the muffler altogether. However, this is not sustainable as a muffler is an important part of your motorcycle. Riding without a muffler can cause engine problems.

One viable solution is to customize your muffler. You can bring it in to resize the opening which will modify the sound of your motorcycle exhaust.

4. Change Your Ignition

Another thing you can modify is the ignition of your motorcycle. A good aftermarket ignition can completely transform the sound of your motorcycle. A good model will reduce the strain and kickback of the motorcycle engine. It will also improve the response timing of your ignition which leads to a stronger and better motorcycle. This affects the sound generated by the motorcycle.

Function Of Motorcycle Exhaust

The motorcycle exhaust is a very important system set in place to help your motorcycle function properly.

Proper Combustion

Combustion of air and fuel is the primary way by which your motorcycle generates energy to power up the motorcycle. It creates toxic by-products such as carbon monoxide. There is also a lot of heat generated.

You wouldn’t want these elements near you or your rider. They can harm your health and the excess heat can burn or damage your boots. An exhaust redirects these outward so that you can drive comfortably.

Improves Engine Performance

The motorcycle exhaust often works hand-in-hand with the motorcycle engine to improve the overall performance of the bike. The exhaust reroutes the by-products to make the system less restrictive. That actually helps increase the horsepower of your motorcycle engine.

The absence of exhaust will just reintroduce the heat in the wrong direction which will generally increase the pressure in the area and mess up with the way your engine functions.

Regulate The Sound

A motorcycle exhaust works both ways in regulating the sound that your ride generates. It generally serves to muffle the noise of your engine. An exhaust redirects heat and other gaseous substances in an organized manner so as to reduce the sound.

Heat, carbon monoxide, and other gaseous compounds are released at highly pressurized rates during combustion. You can expect them to create sounds upon making an impact with hard surfaces. The curvature of exhausts modulates this so as to regulate the sound. Conversely, there are a few things you can do to increase the sound of your motorcycle exhausts.

Strange Motorcycle Noises

Motorcycle sounds serve more purpose than superficial cosmetics. Some noises serve as indicators of more serious insidious problems that you need to resolve immediately.

Locate The Sound

The first step in the diagnosis is to locate the sound. When you hear an unusual sound emanating from your motorcycle, take some time to listen carefully and locate the region from which it came from.

The sounds can be anything, from a mild ticking to a grinding noise. This general inspection allows you to troubleshoot it immediately. Most sounds result from a loose part that you can just screw back on.

Possible Sounds

The different noises pertain to different issues. A grinding sound, whether soft or loud, intermittent or continuous, often means you should replace your brakes or your caliper is stuck.

A crinkling sound can result from corrosion when the motorcycle has not been ridden in a long time. It can also refer to a chain problem which is very dangerous when left unresolved.

A hissing sound can come from a deflating tire. It can also come from a flooded cell battery, a blown gasket, or a radiator leak.

Final Thoughts

Whatever customizations you are planning, make sure to stay within the legal limits of your city. Consult the regulations in place before making drastic changes to your ride. Make sure to consult a motorcycle expert, the local police department, and the inspection station. They will ensure that your motorcycle customizations are legal and will keep the rider safe.

You should also consider the legal limitations of the motorcycle sound. Not everyone favors a loud motorcycle and you could be the recipient of a noise complaint.
