Preparation Steps
Before beginning the installation, ensure that your vehicle is parked on a flat surface and the engine is cool. Gather all the necessary tools and materials listed above.
1. Disconnect the Battery
Start by disconnecting the negative terminal of the battery to prevent any electrical issues during the installation process.
2. Raise the Vehicle
Use a jack to lift the front of the vehicle and secure it with jack stands. Ensure it is stable before proceeding.
Removing the Stock Headers
With the vehicle prepared, you can now begin removing the stock headers.
1. Remove the Exhaust System
Start by removing the exhaust system from the headers. This usually involves unbolting the exhaust pipes and disconnecting any hangers. Keep the hardware in a safe place for reinstallation.
2. Unbolt the Stock Headers
Next, unbolt the stock headers from the engine block. This may require some maneuvering, as space is limited. Be cautious of any remaining gaskets or debris.
Installing the BRZ Headers
Now that the stock headers are removed, it’s time to install the new BRZ headers.
1. Clean the Surface
Use a gasket scraper to clean the surface of the engine block where the headers will mount. Ensure there are no remnants of the old gaskets.
2. Install New Gaskets
Place the new gaskets onto the engine block. Ensure they are aligned properly with the bolt holes.
3. Position the BRZ Headers
Carefully position the BRZ headers onto the engine block, ensuring they fit snugly against the new gaskets.
4. Bolt the Headers in Place
Using your socket wrench, bolt the headers into place. Start with the center bolts and work your way outwards to ensure an even fit.
5. Torque the Bolts
Use a torque wrench to tighten the bolts to the manufacturer’s specifications. This step is crucial to prevent any leaks or damage.
Reinstalling the Exhaust System
With the headers installed, you can now reinstall the exhaust system.
1. Reattach the Exhaust Pipes
Align the exhaust pipes with the new headers and secure them with the original hardware. Make sure everything is tight and aligned properly.
2. Secure the Hangers
Reconnect any hangers that were removed during the disassembly. This ensures the exhaust system is properly supported.
Final Steps
Now that the installation is complete, it’s time for some final checks.
1. Reconnect the Battery
Reconnect the negative terminal of the battery and ensure it is secure.
2. Start the Engine
Start the engine and listen for any unusual noises. Check for exhaust leaks around the headers and exhaust connections.
3. Take a Test Drive
Finally, take your vehicle for a test drive. Pay attention to the sound and performance. You should notice a significant improvement in both areas.
Conclusion
Installing BRZ headers can transform your vehicle’s performance and sound. By following this step-by-step guide, you can ensure a successful installation that enhances your driving experience. Always remember to follow safety precautions and consult a professional if you encounter any issues.
