When it comes to enhancing the performance of your 6.4 HEMI engine, one of the most effective upgrades is the installation of Hedman Hedders. These high-performance headers are designed to improve exhaust flow, increase horsepower, and provide a more aggressive sound. In this article, we will explore the benefits of installing Hedman Hedders on your 6.4 HEMI, along with a step-by-step guide to the installation process.
Benefits of Hedman Hedders
Hedman Hedders are known for their quality construction and performance enhancements. Here are some key benefits of installing these headers on your 6.4 HEMI:
- Increased Horsepower: Hedman Hedders are designed to reduce back pressure, allowing your engine to breathe better and produce more power.
- Improved Torque: Enhanced exhaust flow leads to better torque delivery across the RPM range.
- Durability: Made from high-quality materials, Hedman Hedders are built to withstand high temperatures and resist corrosion.
- Better Sound: The installation of headers changes the exhaust note, providing a deeper and more aggressive sound.
- Easy Installation: Designed for a direct fit, these headers simplify the installation process.
Tools and Materials Needed
Before starting the installation, gather the following tools and materials:
- Hedman Hedders specific for 6.4 HEMI
- Socket set
- Wrench set
- Torque wrench
- Exhaust gasket set
- Anti-seize compound
- Safety glasses
- Gloves
Step-by-Step Installation Process
Step 1: Prepare the Vehicle
Before you begin the installation, ensure your vehicle is parked on a level surface and the engine is cool. Disconnect the battery to prevent any electrical issues during the installation.
Step 2: Remove the Old Exhaust Manifolds
Start by removing the old exhaust manifolds. This involves:
- Removing the heat shields if applicable.
- Unbolting the exhaust pipes from the manifolds.
- Unbolting the manifolds from the engine block.
- Carefully lifting the old manifolds out of the engine bay.
Step 3: Prepare for Hedman Hedders Installation
Clean the surface of the engine block where the new headers will be installed. Ensure there are no old gaskets or debris that could affect the seal. Apply anti-seize compound to the header bolts to prevent them from seizing.
Step 4: Install the Hedman Hedders
Carefully position the Hedman Hedders onto the engine block. Align the bolt holes and insert the bolts by hand. Once all bolts are in place, use a torque wrench to tighten them to the manufacturer’s specifications.
Step 5: Reconnect the Exhaust System
Reconnect the exhaust pipes to the Hedman Hedders. Ensure all connections are secure and use new gaskets to prevent leaks. Tighten all clamps and bolts securely.
Step 6: Reconnect the Battery and Test
Reconnect the battery and start the engine. Listen for any exhaust leaks and check for proper operation. Allow the engine to reach operating temperature and monitor performance.
Conclusion
Installing Hedman Hedders on your 6.4 HEMI can significantly enhance performance, providing an increase in horsepower and torque, along with a more aggressive exhaust note. With the right tools and careful installation, you can enjoy the benefits of this performance upgrade. Remember to follow all safety precautions and consult a professional if you encounter any challenges during the installation process.
