The Subaru BRZ is known for its sleek design and impressive performance, but one of the most sought-after modifications among enthusiasts is achieving that sporty growl. This article will explore how to enhance the sound of your BRZ through the installation of headers and cat-back exhaust systems.
Understanding Exhaust Systems
An exhaust system is designed to expel gases from the engine, but it also plays a crucial role in the sound produced by the vehicle. The two main components that affect sound are the headers and the cat-back exhaust system.
What are Headers?
Headers are aftermarket components that replace the factory exhaust manifolds. They help improve exhaust flow and can significantly alter the sound of your BRZ.
What is a Cat-Back Exhaust System?
A cat-back exhaust system includes all components from the catalytic converter back to the exhaust tips. This system can enhance performance and change the exhaust note, creating a deeper, more aggressive sound.
Benefits of Upgrading to Headers and Cat-Back Exhaust
Upgrading your BRZ’s exhaust components can offer several advantages, including:
- Improved Performance: Better exhaust flow can lead to increased horsepower and torque.
- Enhanced Sound: A sporty growl can make your driving experience more enjoyable.
- Weight Reduction: Aftermarket systems are often lighter than factory components.
Choosing the Right Headers
When selecting headers for your BRZ, consider the following factors:
- Material: Stainless steel is popular for its durability and resistance to corrosion.
- Design: Long-tube headers typically provide better performance, while shorty headers may offer easier installation.
- Brand Reputation: Research brands known for quality and performance in the Subaru community.
Choosing the Right Cat-Back Exhaust System
Similar to headers, selecting a cat-back exhaust system requires careful consideration:
- Sound Level: Choose a system that matches your desired sound profile, from mild to aggressive.
- Tip Design: The exhaust tip design can affect the overall look of your vehicle.
- Fitment: Ensure compatibility with your vehicle’s make and model for optimal performance.
Installation Process
Installing headers and a cat-back exhaust system can be a rewarding DIY project. Here’s a general overview of the installation process:
- Gather Tools: You’ll need basic hand tools, a jack, and jack stands.
- Remove Old Components: Safely lift the vehicle and remove the factory exhaust parts.
- Install Headers: Position the new headers and tighten all connections securely.
- Install Cat-Back System: Follow the manufacturer’s instructions for fitting the new exhaust system.
- Check for Leaks: Start the engine and inspect for any exhaust leaks.
Maintaining Your Exhaust System
To ensure longevity and optimal performance of your headers and cat-back exhaust system, regular maintenance is essential. Here are some tips:
- Inspect Regularly: Check for rust, leaks, and loose connections.
- Clean Components: Remove debris and buildup to maintain airflow.
- Listen for Changes: Pay attention to changes in sound, which may indicate issues.
Conclusion
Upgrading your Subaru BRZ with headers and a cat-back exhaust system can transform its sound and performance. By understanding the components, benefits, and installation process, you can achieve that desired sporty growl and enjoy a more exhilarating driving experience.
