Installing a new header on your vehicle can significantly enhance its performance by increasing torque and power. However, many car enthusiasts believe that such upgrades come with a hefty price tag. This article will guide you through a DIY header installation for under $200, allowing you to boost your vehicle’s performance without breaking the bank.
Understanding Headers
Before diving into the installation process, it’s essential to understand what headers are and how they function. Headers are designed to replace the factory exhaust manifold, allowing exhaust gases to exit the engine more efficiently. This improvement in exhaust flow can lead to increased horsepower and torque.
Benefits of Upgrading to Headers
- Improved Exhaust Flow: Headers reduce back pressure, allowing for a more efficient exhaust system.
- Increased Power: Better exhaust flow translates to more horsepower and torque.
- Better Engine Sound: Headers can enhance the sound of your engine, giving it a more aggressive tone.
- Cost-Effective: Installing headers yourself saves on labor costs.
Tools and Materials Needed
Gathering the right tools and materials is crucial for a successful DIY header installation. Below is a list of what you’ll need:
- New headers
- Gasket set
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Safety glasses
- Gloves
- Exhaust sealant (optional)
Preparation Before Installation
Before starting the installation, it’s important to prepare your workspace and vehicle. Follow these steps:
- Park your vehicle on a flat surface and engage the parking brake.
- Disconnect the battery to prevent any electrical issues.
- Raise the vehicle using a jack and secure it with jack stands.
- Remove any components that may obstruct access to the exhaust manifold, such as the intake or heat shields.
Step-by-Step Installation Process
Now that you have everything prepared, follow these steps to install your new headers:
- Remove the Old Exhaust Manifold: Unbolt the factory manifold using the socket and wrench set. Carefully lift it off and set it aside.
- Clean the Surface: Ensure the surface where the new headers will sit is clean and free of debris.
- Install New Gaskets: Place the new gaskets on the engine block, ensuring they align with the bolt holes.
- Attach the New Headers: Position the new headers over the gaskets and hand-tighten the bolts. Do not fully tighten them yet.
- Torque the Bolts: Use a torque wrench to tighten the header bolts to the manufacturer’s specifications, ensuring an even distribution of pressure.
- Reconnect Components: Reinstall any components you removed earlier, such as the intake or heat shields.
- Reattach the Battery: Connect the battery and ensure all electrical connections are secure.
Post-Installation Tips
After completing the installation, take some time to ensure everything is functioning correctly:
- Check for Leaks: Start the engine and listen for any exhaust leaks around the headers.
- Monitor Performance: Take your vehicle for a test drive to feel the improvements in torque and power.
- Regular Maintenance: Periodically check the header bolts to ensure they remain tight and inspect for any signs of wear.
Conclusion
Installing headers can be an excellent way to enhance your vehicle’s performance without spending a fortune. By following this DIY guide, you can successfully install new headers for under $200, increasing torque and power while enjoying the satisfaction of completing the project yourself. Always remember to prioritize safety and consult your vehicle’s manual for specific instructions related to your make and model.
