The Subaru BRZ is a popular sports car known for its lightweight design and exceptional handling. To enhance its performance and sound, many enthusiasts turn to aftermarket upgrades, with Borla headers being a top choice. In this article, we will explore how Borla headers can maximize performance and deliver an aggressive tone for your Subaru BRZ.
What Are Borla Headers?
Borla headers are high-performance exhaust components designed to improve the flow of exhaust gases from the engine. By replacing the factory exhaust manifold, Borla headers reduce back pressure, allowing the engine to breathe more freely. This results in improved horsepower, torque, and overall engine efficiency.
Benefits of Installing Borla Headers on Your Subaru BRZ
- Increased Horsepower: Borla headers are engineered to enhance engine output, providing a noticeable boost in horsepower.
- Improved Torque: The design of Borla headers allows for better torque delivery, particularly in the mid-range RPMs.
- Enhanced Sound: One of the most appealing aspects of Borla headers is the aggressive exhaust note they produce, giving your BRZ a sporty sound.
- Quality Construction: Borla headers are made from high-quality materials, ensuring durability and longevity.
- Easy Installation: Designed to fit seamlessly, Borla headers are relatively easy to install, especially for those with some mechanical experience.
How Borla Headers Work
To understand the performance benefits of Borla headers, it’s essential to know how they function. The headers replace the factory manifold, which can be restrictive in terms of exhaust flow. By providing a more direct path for exhaust gases to exit the engine, Borla headers reduce back pressure and improve the overall efficiency of the exhaust system.
Design Features of Borla Headers
Borla headers feature several design elements that contribute to their performance:
- Mandrel-Bent Tubing: This design ensures smooth bends in the piping, which minimizes turbulence and maximizes exhaust flow.
- High-Quality Materials: Borla uses T-304 stainless steel, which resists corrosion and provides a long-lasting product.
- Optimized Collector Design: The collectors are designed to enhance exhaust scavenging, further improving performance.
Choosing the Right Borla Headers for Your BRZ
When selecting Borla headers for your Subaru BRZ, consider the following factors:
- Compatibility: Ensure the headers are specifically designed for the Subaru BRZ model year you own.
- Type of Header: Choose between long-tube and shorty headers based on your performance goals and installation preferences.
- Exhaust System Integration: Consider how the headers will work with your existing exhaust system and any other modifications.
Installation Process of Borla Headers
Installing Borla headers can be a rewarding DIY project. Here’s a basic overview of the installation process:
- Gather Tools: You’ll need basic hand tools, a jack, and jack stands for safety.
- Remove the Factory Headers: Disconnect the battery, remove the exhaust system, and unbolt the factory headers.
- Install Borla Headers: Position the new headers and secure them in place, ensuring all gaskets are properly aligned.
- Reconnect Exhaust System: Reattach the exhaust system, ensuring there are no leaks.
- Test Drive: After installation, take your BRZ for a test drive to experience the enhanced performance and sound.
Performance Gains and Sound Characteristics
Many Subaru BRZ owners report significant performance gains after installing Borla headers. These gains can vary, but typical increases include:
- 10-20 HP Increase: Depending on other modifications, users often see an increase of 10 to 20 horsepower.
- Better Throttle Response: Enhanced exhaust flow leads to quicker throttle response and improved acceleration.
- Aggressive Exhaust Note: The distinct sound produced by Borla headers is a favorite among enthusiasts, providing a sporty and aggressive tone.
Conclusion
Upgrading to Borla headers is an excellent way to maximize the performance and sound of your Subaru BRZ. With increased horsepower, improved torque, and an aggressive exhaust note, these headers are a worthwhile investment for any performance enthusiast. Whether you are a seasoned mechanic or a beginner, the installation process is manageable, and the results are sure to impress.
