You can also rejet your carburetor, which will make the engine run richer and produce more noise. Finally, you can install aftermarket slip-on mufflers or full exhaust systems, which are designed to amplify the sound of your Harley’s engine.

  • Purchase a set of aftermarket exhaust pipes for your Harley-Davidson motorcycle

How Can I Make My Motorcycle Stock Exhaust Louder?

If you’re looking to make your motorcycle stock exhaust louder, there are a few things you can do. First, check to see if your exhaust is the right size for your bike. If it’s too small, it will restrict the flow of exhaust and make it quieter. Second, make sure your exhaust is tuned properly.

An improperly tuned exhaust can also restrict flow and cause your motorcycle to sound quieter than it should. Finally, consider adding a baffle or other aftermarket parts to your motorcycle’s exhaust system. This can help increase airflow and amplify the sound of your motorcycle’s engine, making it louder overall.

What Will Make My Harley Louder?

Harley Davidson motorcycles are known for their unique sound. This signature rumble is one of the reasons why many riders choose Harley over other brands. But what if you want your Harley to be even louder?

There are a few things you can do to make your Harley Davidson motorcycle louder. One option is to install aftermarket exhaust pipes. These pipes will increase the flow of exhaust and make your bike sound deeper and more aggressive. Another option is to install an air intake kit.

This will allow more air to flow into the engine, which will create a louder engine noise. Finally, you can also replace the stock muffler with a straight-through muffler or an open baffle muffler. These mufflers don’t have any restrictions on airflow and will make your motorcycle significantly louder than the stock muffler.

Of course, making your Harley Davidson motorcycle louder will also void your warranty so it’s important to weigh the pros and cons before making any modifications. If you decide to go ahead with it, just be sure to ride safely and responsibly!

How Loud is a Stock Harley Exhaust?

If you’re talking about a stock Harley-Davidson motorcycle, they can get pretty loud. Depending on the model, they can range from around 80 decibels to well over 100 decibels. That’s about as loud as a jackhammer or a power saw.

And at peak revs, some models can get even louder than that. So if you’re looking for a quiet ride, a stock Harley might not be the best choice.

How Many Decibels is a Harley With Straight Pipes?

Harley-Davidson motorcycles are known for their signature rumble, which is often amplified by aftermarket exhaust modifications like straight pipes. But how loud is a Harley with straight pipes, really?

The short answer is that it depends on a number of factors, including the size of the engine, the type of exhaust system, and whether or not the motorcycle has been modified to increase noise output. That said, most Harleys with straight pipes fall somewhere between 95 and 110 decibels.

To put that into perspective, a typical conversation occurs at around 60 decibels, while an ambulance siren clocks in at 120 decibels.

So yes, straight-piped Harleys are pretty darn loud – but there are ways to make them even louder if you’re so inclined.

If you’re thinking about adding straight pipes to your Harley (or any other motorcycle), just be aware that they can be quite loud – especially at higher speeds. It’s always a good idea to wear earplugs when riding – both for your own safety and for the sake of those around you!

Removing Baffles from Stock Harley Exhaust

If you’re looking to boost the performance of your Harley, one of the first places to start is by removing the baffles from your stock exhaust.

This simple modification can make a big difference in both power and sound, giving your bike a more aggressive tone and increasing its overall output. Of course, before you start tinkering with your exhaust, it’s important to understand what you’re doing and why. In this blog post, we’ll walk you through the process of removing baffles from a stock Harley exhaust, as well as some of the potential benefits and drawbacks of this upgrade. The first thing you’ll need to do is remove the heat shield from your exhaust pipe.

This will give you access to the baffles that need to be removed. Once the heat shield is out of the way, take a look at how the baffles are attached to the pipe. In most cases, they will be welded in place or held in with bolts.

If they are welded, you’ll need to use a grinder or cutting tool to remove them. If they are bolted in place, simply remove the bolts and set them aside. With the baffles out of the way, there should be a noticeable difference in both sound and power. Your bike will be louder and have an improved throttle response.

You may also see a slight increase in top speed due to reduced back pressure. However, there are some potential downsides to consider as well before making this modification permanent. First off, removing baffles can significantly increase noise levels both for yourself and those around you.

This may not be an issue if you only ride on private property or during legal noise hours, but it’s something worth considering nonetheless. Additionally, without baffles directing airflow through your muffler packing material can overheat quickly, potentially leading to damage or even failure of your exhaust system down the road.

As such, it’s generally advisable to only ride without baffles for short periods of time until you can install an aftermarket muffler designed for use without them. So there you have it: everything you need to know about removing baffles from your stock Harley exhaust.

How to Make Vance And Hines Pipes Louder

If you want to make your Vance and Hines pipes louder, there are a few things you can do. First, check to see if the baffles are installed. If they are, remove them. Next, drill out the rivets that hold the end caps on and replace them with bolts. Finally, re-jet your carburetor for optimum performance. Doing these things should give you the extra volume you’re looking for.

Harley Davidson Stock Exhaust Modification

Harley-Davidson is known for its stylish and powerful motorcycles. But what many riders don’t realize is that the stock exhaust on most Harley’s is actually quite restrictive. That’s why many riders choose to modify their exhaust systems, in order to experience greater power and performance.

There are a few different ways that you can go about modifying your Harley’s exhaust system. One popular option is to install a set of aftermarket pipes. Aftermarket pipes are usually larger in diameter than stock, which allows for better airflow and therefore more power.

They also tend to be lighter weight, which can further improve performance. Another option is to install an aftermarket muffler. This can also help increase power, while also giving your bike a unique sound.

There are many different styles of aftermarket mufflers available, so you can find one that fits your personal taste and riding style perfectly. Of course, there are other modifications you can make to your Harley’s exhaust system as well.

For example, you could install headers or high-flow air filters. But no matter what route you choose to take, remember that safety should always come first – so be sure to consult with a professional mechanic before making any changes to your bike’s exhaust system!


If you want to make your stock Harley pipes louder, there are a few things you can do. First, check to see if your mufflers are installed correctly and that the baffles aren’t loose. If everything looks good there, then you can try drilling holes in the exhaust pipe itself. This will create more of an open area for the exhaust to flow through, which will make it louder.

You can also remove the spark arrestors from the end of the pipes, which will also help increase noise levels.
