Upgrading your Nissan 370Z with new headers can significantly improve performance and sound. However, the installation process can be complex. Here are some tips to ensure a smooth upgrade.
Understanding Headers
Headers are part of the exhaust system, designed to improve the flow of exhaust gases from the engine. By replacing the factory exhaust manifold with aftermarket headers, you can enhance horsepower and torque.
Tools and Materials Needed
- Socket set
- Wrenches
- Torque wrench
- Jack and jack stands
- Header gaskets
- Anti-seize compound
- Safety glasses
- Gloves
Preparation Steps
Before starting the installation, ensure you have all the necessary tools and materials ready. Here’s how to prepare:
- Park your vehicle on a flat surface.
- Disconnect the battery to prevent any electrical issues.
- Lift the car using a jack and secure it with jack stands.
Removing the Stock Headers
To install the new headers, you first need to remove the stock ones. Follow these steps:
- Remove any components obstructing access to the headers, such as the air intake.
- Unbolt the stock headers from the engine and the exhaust system.
- Carefully remove the old headers and gaskets.
Installing the New Headers
With the old headers removed, it’s time to install the new ones. Here’s how:
- Apply anti-seize compound to the header bolts to prevent them from seizing.
- Position the new headers in place and align them with the exhaust ports.
- Hand-tighten the bolts to secure the headers, ensuring they are correctly aligned.
- Use a torque wrench to tighten the bolts to the manufacturer’s specifications.
Reassembling the Exhaust System
After the headers are securely installed, you’ll need to reassemble the exhaust system:
- Reconnect the exhaust pipes to the new headers.
- Ensure all connections are tight and leak-free.
- Reinstall any components that were removed for access.
Final Checks
Once everything is reassembled, it’s important to perform a few final checks:
- Reconnect the battery.
- Start the engine and listen for any unusual sounds.
- Check for exhaust leaks around the headers and connections.
Conclusion
Installing new headers on your 370Z can be a rewarding DIY project that enhances your vehicle’s performance. By following these tips and taking your time, you can achieve a successful upgrade.
