by

Installing Hedman Challenger Headers can significantly enhance your vehicle’s performance by improving exhaust flow and increasing horsepower. This step-by-step guide will walk you through the installation process, ensuring that you can upgrade your vehicle with confidence.

Tools and Materials Needed

  • Hedman Challenger Headers
  • Socket set
  • Torque wrench
  • Ratchet and extensions
  • Wrench set
  • Gasket scraper
  • Header gaskets
  • High-temperature exhaust sealant
  • Safety glasses
  • Gloves

Preparation Steps

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

  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent any electrical issues.
  • Lift the vehicle using a jack and secure it with jack stands.
  • Remove any components that obstruct access to the exhaust manifold, such as the air intake or heat shields.

Removing the Old Exhaust Manifold

To install the new headers, the old exhaust manifold must be removed. Follow these steps:

  • Locate the bolts holding the exhaust manifold in place and remove them using a socket or wrench.
  • Carefully detach the exhaust manifold from the engine block.
  • Remove the old gasket and clean the surface of the engine block with a gasket scraper to ensure a proper seal.

Installing the Hedman Challenger Headers

With the old manifold removed, you can now install the Hedman Challenger Headers:

  • Position the new header in place, aligning it with the bolt holes on the engine block.
  • Install the header gaskets on the engine block.
  • Secure the headers using the provided bolts, tightening them by hand first.
  • Use a torque wrench to tighten the bolts to the manufacturer’s specifications, ensuring even pressure across the header.

Connecting the Exhaust System

Next, you’ll need to connect the headers to the rest of the exhaust system:

  • Align the collector of the headers with the exhaust pipe.
  • Use the appropriate clamps to secure the connection, ensuring a tight fit.
  • Apply high-temperature exhaust sealant to prevent leaks.

Final Checks and Reassembly

Before finishing up, perform the following checks:

  • Double-check all connections and bolts to ensure everything is secure.
  • Reconnect any components that were removed during the installation.
  • Reconnect the battery.

Testing the Installation

Once everything is reassembled, it’s time to test your new headers:

  • Start the engine and listen for any unusual sounds that could indicate a leak.
  • Check for leaks around the headers and exhaust connections.
  • Take the vehicle for a short drive to ensure everything is functioning correctly.

Conclusion

Installing Hedman Challenger Headers can be a rewarding project that enhances your vehicle’s performance. By following these steps, you can ensure a successful installation and enjoy the benefits of improved exhaust flow and horsepower.
