Tools and Materials Needed
- Invidia Miata Headers
- Socket set
- Wrench set
- Torque wrench
- Gasket scraper

- Safety glasses
- Gloves
Preparation
Before starting the installation, ensure that you have all the necessary tools and materials at hand. It’s important to work in a well-ventilated area and to wear safety gear, including gloves and safety glasses, to protect yourself during the process.
Step 1: Raise the Vehicle
Using a jack, raise the front of the Miata and secure it with jack stands. This will provide you with enough space to work comfortably under the vehicle.
Step 2: Remove the Existing Exhaust System
Start by removing the existing exhaust system. Begin at the exhaust manifold and work your way back. Use a socket set to remove the bolts connecting the exhaust manifold to the engine block.
Next, detach the exhaust pipes from the manifold and any hangers that may be holding the exhaust system in place. Be sure to keep track of all the bolts and hangers for reinstallation.
Step 3: Clean the Exhaust Ports
Once the old exhaust system is removed, use a gasket scraper to clean the exhaust ports on the engine. This ensures a proper seal when you install the new headers.
Step 4: Install the New Invidia Headers
Position the Invidia headers onto the engine block. Make sure that the header flanges align with the exhaust ports. Insert the new exhaust gaskets between the headers and the engine block.
Using a torque wrench, tighten the bolts to the manufacturer’s specifications. It’s crucial to follow the correct torque sequence to avoid warping the headers or causing leaks.
Step 5: Reattach the Exhaust System
With the headers securely in place, begin reattaching the exhaust system. Start by connecting the exhaust pipes to the new headers, ensuring a snug fit.
Reinstall any hangers and brackets that were removed earlier. Make sure everything is aligned correctly to prevent any vibrations or rattles.
Step 6: Lower the Vehicle and Test
Once everything is reattached, carefully lower the vehicle back to the ground. Start the engine and listen for any unusual sounds that may indicate a leak or improper installation.
Step 7: Final Checks
After the initial test, take the Miata for a short drive to ensure everything is functioning properly. Pay attention to the sound and performance changes, which should be noticeably improved with the new headers.
Conclusion
The installation of Invidia Miata headers is a straightforward process that can significantly enhance your vehicle’s sound and performance. By following this step-by-step guide, you can successfully complete the installation and enjoy the benefits of your new headers.
