The Honda Accord V6 is a popular vehicle known for its reliability and performance. One of the most effective modifications to enhance both power and sound is the installation of aftermarket headers. This guide will walk you through the process of installing headers on your Honda Accord V6, helping you gain up to 15 horsepower and improve your vehicle’s exhaust note.
Understanding Headers
Headers are designed to replace the factory exhaust manifold. They improve exhaust flow, which can lead to better engine performance. Here are some key benefits of upgrading to headers:
- Increased horsepower and torque
- Improved exhaust sound
- Better fuel efficiency
Tools and Materials Needed
Before starting the installation process, gather the following tools and materials:
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Header gaskets
- Aftermarket headers
- Exhaust sealant (optional)
- Safety glasses and gloves
Preparation Steps
Proper preparation is crucial for a successful header installation. Follow these steps:
- Park your vehicle on a level surface.
- Disconnect the battery to prevent electrical issues.
- Lift the front of the car using the jack and secure it with jack stands.
- Remove any underbody panels that may obstruct access to the exhaust system.
Removing the Old Exhaust Manifold
To install the new headers, you must first remove the old exhaust manifold. Follow these steps:
- Locate the exhaust manifold and identify the bolts securing it.
- Using the socket set, carefully remove the bolts.
- Disconnect any sensors or hoses attached to the manifold.
- Remove the old manifold and gaskets from the engine.
Installing the New Headers
Now that the old manifold is removed, it’s time to install the new headers:
- Position the new headers onto the engine, ensuring proper alignment with the exhaust ports.
- Install the new header gaskets to prevent exhaust leaks.
- Secure the headers using the provided bolts, tightening them in a crisscross pattern for even pressure.
- Reconnect any sensors or hoses that were disconnected during removal.
Connecting the Exhaust System
After installing the headers, the next step is to connect the exhaust system:
- Align the headers with the rest of the exhaust system.
- Secure the connection using the appropriate clamps or bolts.
- If necessary, apply exhaust sealant to ensure a tight seal.
Final Steps
With the headers installed and the exhaust system connected, complete the following final steps:
- Double-check all connections and bolts for tightness.
- Reconnect the battery.
- Start the engine and listen for any unusual sounds that may indicate a leak.
- Take the vehicle for a test drive to experience the performance improvements.
Conclusion
Installing headers on your Honda Accord V6 is a rewarding modification that can significantly enhance both performance and sound. By following this guide, you can gain up to 15 horsepower and enjoy a more aggressive exhaust note. Always remember to prioritize safety and consult a professional if you’re unsure about any part of the installation process.
