The Toyota GR86 has made a name for itself in the automotive world, known for its lightweight design and exceptional handling. One of the most significant upgrades that enthusiasts consider is the installation of Agency Power headers. This modification not only enhances the sound but also improves performance in various ways.
Understanding Agency Power Headers
Agency Power headers are designed to replace the factory exhaust manifold, allowing for better exhaust flow and increased performance. By optimizing the exhaust system, these headers contribute to a more aggressive sound and improved engine efficiency.
Benefits of Upgrading to Agency Power Headers
- Improved Exhaust Flow: The design of Agency Power headers allows for a smoother exit of exhaust gases, reducing back pressure and increasing horsepower.
- Enhanced Sound: The headers produce a deeper, more aggressive exhaust note that enhances the driving experience.
- Weight Reduction: Made from lightweight materials, these headers can help reduce overall vehicle weight.
- Durability: Constructed with high-quality materials, Agency Power headers are built to withstand high temperatures and resist corrosion.
How Headers Impact Performance
When it comes to performance, headers play a crucial role in the engine’s ability to breathe. By reducing restrictions in the exhaust system, headers allow the engine to expel exhaust gases more efficiently. This leads to several performance benefits, including:
- Increased Horsepower: With better exhaust flow, the engine can produce more power, translating to improved acceleration.
- Better Torque: Headers can enhance torque at various RPMs, making the vehicle more responsive during everyday driving.
- Fuel Efficiency: Improved exhaust flow can also lead to better fuel efficiency, as the engine works more effectively.
Installation Process
Installing Agency Power headers on your GR86 can be a rewarding project, but it requires some mechanical knowledge. Here’s a general overview of the installation process:
- Preparation: Gather all necessary tools and ensure the vehicle is securely lifted.
- Remove Factory Headers: Disconnect the exhaust system and remove the factory headers carefully.
- Install New Headers: Position the Agency Power headers and secure them in place, ensuring all connections are tight.
- Reconnect Exhaust System: Reattach the exhaust system and check for leaks.
- Test Drive: Start the vehicle and take it for a test drive to ensure everything is functioning correctly.
Sound Characteristics of Agency Power Headers
One of the most noticeable changes after installing Agency Power headers is the sound. The headers produce a rich, throaty growl that enhances the sporty character of the GR86. This change in exhaust note can be attributed to:
- Header Design: The tuned design of the headers allows for a more aggressive sound profile.
- Material Quality: High-grade materials contribute to a deeper sound without excessive noise.
- Exhaust Flow Dynamics: Improved flow dynamics help create a more resonant and appealing exhaust note.
Conclusion
Upgrading to Agency Power headers is an excellent way to enhance both the sound and performance of your Toyota GR86. With improved exhaust flow, increased horsepower, and a more aggressive exhaust note, this modification is a favorite among enthusiasts. Whether you’re looking to improve your daily driving experience or take your GR86 to the track, Agency Power headers are a worthwhile investment.
