Preparation Steps

Before starting the installation, it’s essential to prepare your workspace and vehicle. Follow these steps:

  • Ensure your vehicle is parked on a flat surface.
  • Disconnect the negative battery terminal to prevent any electrical issues.
  • Lift the vehicle using a jack and secure it with jack stands.
  • Remove any components obstructing access to the exhaust manifold, such as the intake or engine cover.

Removing the Stock Headers

To install the GReddy headers, you must first remove the existing stock headers. Follow these steps:

  • Locate the bolts securing the stock headers to the engine.
  • Using a socket set, carefully remove the bolts. Keep them in a safe place for reinstallation of other components.
  • Disconnect the exhaust pipe from the stock headers.
  • Remove the stock headers from the engine bay. You may need to wiggle them free gently.

Preparing for Installation

With the stock headers removed, it’s time to prepare the area for the new GReddy headers:

  • Clean the exhaust manifold surface using a gasket scraper to remove any old gasket material.
  • Inspect the area for any signs of damage or wear that may need attention.
  • Apply a thin layer of high-temperature RTV sealant on the new gaskets for a better seal.

Installing the GReddy Headers

Now it’s time to install the new GReddy headers. Follow these steps carefully:

  • Position the new headers onto the engine, aligning them with the bolt holes.
  • Insert the bolts and hand-tighten them to hold the headers in place.
  • Using a torque wrench, tighten the bolts to the manufacturer’s specified torque settings in a crisscross pattern.
  • Reconnect the exhaust pipe to the new headers, ensuring a snug fit.

Final Steps and Testing

After the installation is complete, follow these final steps to ensure everything is functioning correctly:

  • Reconnect the negative battery terminal.
  • Start the vehicle and listen for any unusual sounds that might indicate a leak.
  • Check for leaks around the header and exhaust pipe connections.
  • Take the vehicle for a short drive to ensure everything is working properly.

Conclusion

Installing GReddy headers can be a rewarding experience that enhances your vehicle’s performance and sound. By following this step-by-step guide, you can ensure a successful installation and enjoy the benefits of your new headers.
