What’s the Best Way to Enhance the Engine Sound of a Toyota GT86 with an Aftermarket Exhaust?

When you’re looking to add a bit of growl to your Toyota GT86, an aftermarket exhaust system is a go-to modification. Not only can this upgrade amplify the revving of your engine, but it can also improve the overall performance and power of your vehicle. In this article, we’ll delve into the best ways to enhance your GT86 engine sound with an aftermarket exhaust, providing helpful tips and insights along the way. Let’s rev things up!

The Power of Aftermarket Exhaust

The stock exhaust system in an automobile does an excellent job of expelling exhaust gases from the engine and reducing noise. But for many car enthusiasts, a stock exhaust simply doesn’t offer the punchy power and performance, and that distinctive sound that comes with a high-performance exhaust system.

Many aftermarket exhaust systems are designed to increase the power output of your engine by improving its exhaust flow. Brands like Subaru and Toyota understand the need for performance optimization in their vehicles and often focus on producing high-end sports cars, such as the GT86, that benefit greatly from aftermarket exhaust systems.

By reducing the back pressure and allowing a free flow of exhaust gases, aftermarket exhausts can improve the engine’s performance. Additionally, the unique sound produced is something many car enthusiasts crave, bringing an extra level of enjoyment to your driving experience.

Choosing the Right Exhaust System

When it comes to choosing the right exhaust system for your Toyota GT86, there are a few factors to consider. First, you need to determine what you want to achieve with your new exhaust. Are you looking for a deeper, throatier sound, or are you more interested in improving your car’s performance?

Racing exhausts are popular among drivers who want a high-performance sound and look. These exhausts are typically louder and produce a more aggressive, raw engine note. They are also designed for maximum power and performance, making them a suitable choice for those looking to enhance both the sound and speed of their GT86.

On the other hand, if you’re after a modest increase in sound and performance, a cat-back exhaust system might be a better choice. These systems replace the stock exhaust from the catalytic converter back and offer a good balance between performance, price, and noise level.

The Sound of Power

The exhaust system is responsible for creating the iconic sound that so many car enthusiasts love. To put it simply, the more freely the exhaust gases can flow out of the engine, the louder and more powerful the sound will be.

This sound is created by the exhaust gases passing through the exhaust pipe and resonating within the exhaust system. The louder the sound, the more power your car is likely to have. This is why many performance cars, like the Toyota GT86, have unique, high-pitched exhaust notes. The right aftermarket exhaust can enhance this sound, making your car sound more powerful and aggressive.

Installation Tips

Once you’ve chosen the right aftermarket exhaust for your GT86, it’s time for installation. While some car enthusiasts prefer to take their vehicle to a professional, others opt for the DIY route.

Before beginning the installation, ensure you have all the necessary tools and equipment. This normally includes a socket set, wrenches, and a car jack. Also, it’s important to wear safety goggles and gloves, as rust and debris can easily fall from the exhaust during removal.

First, carefully remove the stock exhaust system from your vehicle. Next, fit the aftermarket exhaust in the same location, ensuring it’s securely fastened. Finally, start your engine and listen to the sound. If you hear any unusual noises or rattling, re-check the installation to ensure everything is secure.

The Long-Term Impact

A quality aftermarket exhaust system is a long-term investment for your Toyota GT86. Not only will it enhance the sound of your vehicle, but it will also improve performance, fuel efficiency, and potentially your vehicle’s resale value. Remember, a good exhaust system doesn’t just sound good – it’s a sign of a healthy, high-performance engine.

Choosing the right product for your vehicle will help ensure you achieve the desired sound and performance. Whether you’re a car enthusiast looking for a throaty roar or a daily driver wanting a smooth, sporty sound, an aftermarket exhaust can provide the ideal solution.

As car enthusiasts, enhancing the sound and performance of our vehicles brings us joy. However, it’s crucial to remember that safety is paramount. Always ensure your modifications comply with local noise regulations and that your vehicle is maintained regularly to ensure optimal performance and safety.

The Role of Key Components in an Exhaust System

The exhaust system of a Toyota GT86, or any other car for that matter, comprises several key components. Each plays a critical role in dictating the sound and performance of the car.

The exhaust manifold, affixed to the engine, collects exhaust gases from the engine’s cylinders which then flow into the front pipe. A well-designed and high quality manifold will ensure optimal exhaust flow, contributing to both power and sound.

Next comes the catalytic converter, which reduces harmful emissions. The performance and sound of your GT86 will not be much affected by this component. However, in a catback exhaust system, this is the point from which the system is replaced.

The muffler, also known as the silencer, is key in determining the sound of your exhaust. A racing exhaust, for example, contains less sound-dampening material, leading to a louder exhaust note.

The pipe diameter is another crucial factor. A larger diameter allows for more exhaust flow, contributing to a boost in horsepower torque. However, it’s important to bear in mind that the optimal diameter will depend on your specific engine and modifications.

Lastly, the exhaust tip, often adorned with an exhaust logo, impacts the sound and aesthetic of your car. Some tips are designed to amplify sound, while others focus on creating a unique exhaust note.

The Effect of Complementary Modifications

While an aftermarket exhaust system can significantly enhance the sound and performance of your Toyota GT86, complementary modifications can take these improvements even further.

Adding an air filter can increase the flow of cold air into the engine, leading to better combustion and therefore increased power. Brands like Subaru BRZ and Scion Toyota offer high-performance air filters compatible with the GT86.

Upgrading to a performance header, which includes the exhaust manifold and front pipe, can also provide substantial benefits. A high-quality header from a brand like Subaru BRZ or Scion Toyota will ensure optimal exhaust flow, contributing to a more powerful engine and a more aggressive exhaust note.

Another modification to consider is an axle exhaust. This type of system replaces the exhaust piping from the rear axle to the exhaust tip, enhancing both sound and performance.


Choosing and installing an aftermarket exhaust system for your Toyota GT86 is about more than just amplifying the sound. It’s about improving the overall driving experience, boosting your vehicle’s performance, and expressing your personality and passion for cars.

Remember, different components like the muffler, pipe diameter, and exhaust tip, all contribute to the final sound and performance. Also consider complementary modifications, like an air filter or axle exhaust, to further enhance your GT86.

Many brands offer high-quality components that can transform your driving experience. Whether it’s a Subaru BRZ air filter or a Scion Toyota header, investing in these components can make a significant difference. However, always ensure that your modifications comply with local noise regulations and that your vehicle is regularly maintained.

Finally, take pride in your vehicle and the modifications you make. Whether you’re a car enthusiast looking for a throaty roar, or simply want a smoother, sportier drive, all that matters is that your GT86 brings you joy on every journey.
