The Subaru BRZ has gained a reputation for being a fun and sporty coupe, but many enthusiasts look for ways to enhance its performance and sound. One popular modification among BRZ owners is the installation of aftermarket headers, particularly Kooks headers. In this article, we will explore the sound comparison and power gains associated with Kooks headers for the Subaru BRZ.
What Are Kooks Headers?
Kooks Headers is a well-known brand in the aftermarket automotive industry, specializing in high-performance exhaust systems. Their headers are designed to improve exhaust flow, enhance engine performance, and create a more aggressive sound profile. For the Subaru BRZ, Kooks offers a range of headers that cater to different performance needs and preferences.
Benefits of Upgrading to Kooks Headers
- Improved Performance: Kooks headers are designed to optimize exhaust flow, which can lead to increased horsepower and torque.
- Enhanced Sound: The installation of Kooks headers significantly changes the exhaust note, providing a deeper and more aggressive sound.
- Quality Construction: Kooks headers are made from high-quality materials, ensuring durability and longevity.
- Custom Fit: Designed specifically for the Subaru BRZ, these headers fit perfectly without the need for extensive modifications.
Sound Comparison: Stock vs. Kooks Headers
One of the most noticeable changes when upgrading to Kooks headers is the difference in sound. The stock exhaust system of the Subaru BRZ has a relatively subdued tone, which some enthusiasts find lacking. In contrast, Kooks headers provide a more aggressive and throaty exhaust note. Below, we will compare the sound characteristics of both systems.
Stock Exhaust Sound
The stock exhaust system of the Subaru BRZ is designed for a balance between performance and comfort. While it provides a decent sound, it is often described as being too quiet, especially under acceleration. The sound lacks the depth and character that many sports car enthusiasts seek.
Kooks Headers Sound
In contrast, Kooks headers dramatically alter the exhaust sound. The installation of these headers results in a deeper, more resonant tone that is sure to turn heads. The sound is more pronounced under acceleration, providing an exhilarating driving experience. Many owners report that the car sounds more like a true sports car after the upgrade.
Power Gains with Kooks Headers
Aside from the sound enhancements, Kooks headers also contribute to increased power output. The improved exhaust flow allows the engine to breathe more freely, which can lead to significant gains in horsepower and torque. Here, we will discuss the expected power gains when installing Kooks headers on a Subaru BRZ.
Dyno Results
Many enthusiasts have reported their dyno results after installing Kooks headers. On average, users can expect to see power gains of:
- Horsepower: Gains of 10-15 horsepower are common.
- Torque: Increases of 8-12 lb-ft of torque can also be observed.
Real-World Performance
In real-world driving conditions, these power gains translate to improved acceleration and responsiveness. Drivers often report a noticeable difference in throttle response, making the BRZ feel more lively and engaging to drive. The combination of enhanced sound and increased power makes Kooks headers a popular choice among BRZ owners.
Installation Considerations
Installing Kooks headers on a Subaru BRZ is a task that can be tackled by experienced DIY enthusiasts, but it does require some mechanical knowledge and tools. It is recommended to follow a detailed installation guide or seek professional assistance if you are unsure about the process.
Tools Needed
- Socket set
- Wrenches
- Torque wrench
- Jack and jack stands
- Safety glasses
Steps for Installation
The installation process generally involves the following steps:
- Lift the vehicle and secure it on jack stands.
- Remove the stock exhaust manifold.
- Install the Kooks headers following the manufacturer’s instructions.
- Reattach the exhaust system and check for leaks.
- Lower the vehicle and start the engine to check the sound and performance.
Conclusion
Kooks headers are a fantastic upgrade for Subaru BRZ owners looking to enhance both sound and performance. With significant power gains and a more aggressive exhaust note, these headers provide an exciting driving experience. Whether you are a casual driver or a dedicated enthusiast, Kooks headers can take your BRZ to the next level.
