The installation of MagnaFlow headers on a Miata can significantly enhance performance and power output. This guide will provide a detailed, step-by-step process to ensure a successful installation, maximizing your vehicle’s potential.
Tools and Materials Needed
- MagnaFlow Miata Headers
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Exhaust gasket
- Anti-seize compound
- Safety glasses
- Gloves
Preparation
Before starting the installation, ensure you have all the necessary tools and materials ready. It’s also important to prepare your workspace to allow for easy access to the vehicle and components.
1. Safety First
Always wear safety glasses and gloves to protect yourself from debris and sharp edges. Make sure the vehicle is parked on a flat surface and engage the parking brake.
2. Lift the Vehicle
Using a jack, lift the front of the Miata and secure it with jack stands. Ensure the vehicle is stable before proceeding with the installation.
Removing the Old Headers
To install the new MagnaFlow headers, you will first need to remove the existing headers from the vehicle.
1. Disconnect the Battery
Start by disconnecting the negative terminal of the battery to prevent any electrical issues during the installation process.
2. Remove the Exhaust System
Unbolt and remove the exhaust system from the headers. This may require some effort, especially if the bolts are rusted. Use penetrating oil if necessary.
3. Unbolt the Old Headers
Locate the bolts securing the old headers to the engine. Use a socket or wrench to carefully unbolt them. Keep track of the bolts for reuse.
4. Remove the Old Headers
Once unbolted, carefully remove the old headers from the engine bay. Be cautious of any sharp edges or hot surfaces.
Installing the MagnaFlow Headers
Now that the old headers are removed, it’s time to install the new MagnaFlow headers.
1. Prepare the New Headers
Before installation, apply anti-seize compound to the threads of the bolts to prevent seizing in the future. Ensure the new headers are clean and ready for installation.
2. Position the New Headers
Carefully position the new MagnaFlow headers into place, aligning them with the exhaust ports on the engine.
3. Bolt the Headers in Place
Using the original bolts, secure the new headers to the engine. Start by hand-tightening them, then use a torque wrench to tighten them to the manufacturer’s specifications.
4. Reattach the Exhaust System
Reconnect the exhaust system to the new headers, ensuring all connections are secure and properly aligned.
Final Steps
With the new headers installed, there are a few final steps to complete the process.
1. Reconnect the Battery
Reconnect the negative terminal of the battery, ensuring a secure connection.
2. Lower the Vehicle
Carefully lower the vehicle back to the ground using the jack. Remove the jack stands and ensure the vehicle is stable.
3. Start the Engine
Start the engine and listen for any unusual noises. Check for leaks around the headers and exhaust system. If everything sounds and looks good, you have successfully installed the MagnaFlow headers!
Conclusion
Installing MagnaFlow headers on your Miata can lead to significant power gains and improved performance. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of enhanced exhaust flow. Always remember to take safety precautions and consult with a professional if you encounter any issues during the installation process.
