The Subaru WRX is known for its impressive performance and rally heritage. One of the most popular modifications among enthusiasts is the installation of Borla headers. These headers not only enhance the sound of the exhaust but also provide significant power improvements.
What Are Borla Headers?
Borla headers are aftermarket exhaust components designed to replace the factory exhaust manifold. They are crafted from high-quality materials and engineered to improve exhaust flow, resulting in better engine performance.
Benefits of Installing Borla Headers
- Increased Horsepower: Borla headers are designed to optimize exhaust flow, which can lead to noticeable gains in horsepower.
- Enhanced Sound: One of the most appealing aspects of Borla headers is the aggressive exhaust note they produce, giving the WRX a more powerful sound.
- Improved Torque: By reducing back pressure, Borla headers can enhance torque delivery across the RPM range.
- Durability: Made from high-quality stainless steel, Borla headers are built to last and resist corrosion.
Installation Process
Installing Borla headers on a Subaru WRX can be a rewarding project. However, it requires some mechanical knowledge and tools. Here’s a basic overview of the installation process:
- Gather Tools and Materials: You will need a socket set, wrenches, and potentially a lift or jack stands.
- Remove the Factory Headers: Disconnect the battery and remove any components obstructing access to the headers.
- Install Borla Headers: Position the Borla headers and secure them to the engine block and exhaust system.
- Reconnect Components: Reinstall any parts that were removed and reconnect the battery.
Performance Improvements
Many Subaru WRX owners report noticeable performance improvements after installing Borla headers. These improvements can include:
- Throttle Response: Enhanced throttle response is often cited, allowing for quicker acceleration.
- Power Band: A wider power band can be experienced, making the car feel more responsive at various speeds.
- Fuel Efficiency: In some cases, drivers have reported improved fuel efficiency due to better engine performance.
Sound Characteristics
The sound produced by Borla headers is one of the key selling points. The headers provide a deeper, more aggressive tone compared to stock headers. This change in sound can be particularly appealing for those who enjoy a sporty driving experience.
Considerations Before Installation
Before proceeding with the installation of Borla headers, consider the following:
- Legal Regulations: Check local laws regarding emissions and modifications to ensure compliance.
- Warranty Implications: Installing aftermarket parts may void certain warranties; consult with your dealer.
- Professional Installation: If unsure about the installation process, consider hiring a professional mechanic.
Conclusion
Borla headers are a popular upgrade for Subaru WRX enthusiasts looking to enhance both performance and sound. With their ability to increase horsepower, improve torque, and provide a more aggressive exhaust note, they represent a worthwhile investment for those looking to elevate their driving experience.
