The .7 HEMI engine is known for its power and performance, but upgrading to high-performance headers can significantly enhance its capabilities. This guide will walk you through the process of installing ceramic coated headers, taking your engine from stock to over 500 horsepower.
Understanding the Benefits of Ceramic Coated Headers
Ceramic coated headers provide several advantages over traditional headers, including:
- Heat Resistance: Ceramic coatings can withstand higher temperatures, reducing under-hood heat.
- Improved Exhaust Flow: Enhanced design allows for better exhaust flow, increasing overall horsepower.
- Corrosion Resistance: The coating protects against rust and corrosion, extending the life of your headers.
- Better Aesthetics: Ceramic coatings often look cleaner and more polished than raw metal.
Tools and Materials Needed
Before beginning the installation, gather the following tools and materials:
- Socket set
- Wrench set
- Torque wrench
- Jack and jack stands
- Header gaskets
- New bolts
- Anti-seize compound
- Safety glasses and gloves
Step-by-Step Installation Process
1. Prepare Your Vehicle
Start by parking your vehicle on a flat surface. Engage the parking brake and disconnect the battery to ensure safety during installation.
2. Raise the Vehicle
Using a jack, lift the front of the vehicle and secure it with jack stands. Ensure the vehicle is stable before proceeding.
3. Remove the Stock Headers
Begin by removing the bolts that secure the stock headers to the engine. Carefully detach any exhaust pipes connected to the headers, and remove the old headers from the engine bay.
4. Clean the Surface
Once the stock headers are removed, clean the surface of the engine where the new headers will be installed. Ensure there is no debris or old gasket material left behind.
5. Install New Header Gaskets
Place the new header gaskets onto the engine surface, ensuring they are aligned correctly with the bolt holes.
6. Install the Ceramic Coated Headers
Carefully position the ceramic coated headers onto the gaskets. Start inserting the bolts by hand to avoid cross-threading.
7. Torque the Bolts
Using a torque wrench, tighten the header bolts to the manufacturer’s specifications. This ensures a proper seal and prevents leaks.
8. Reattach Exhaust Pipes
Reconnect any exhaust pipes that were removed during the process. Ensure all connections are secure and leak-free.
9. Lower the Vehicle and Reconnect the Battery
Carefully lower the vehicle back to the ground and remove the jack stands. Reconnect the battery, ensuring all connections are tight.
10. Start the Engine
Start the engine and listen for any unusual noises. Check for exhaust leaks around the headers. If everything sounds good, take the vehicle for a test drive.
Final Thoughts
Installing ceramic coated headers on your .7 HEMI can significantly boost performance and efficiency. With the right tools and careful installation, you can achieve over 500 horsepower, enhancing your driving experience.
Maintenance Tips for Your Headers
To ensure the longevity and performance of your ceramic coated headers, consider the following maintenance tips:
- Regularly check for exhaust leaks and tighten bolts as necessary.
- Keep the headers clean to prevent build-up of dirt and grime.
- Inspect the condition of the gaskets periodically and replace them if needed.
- Avoid excessive idling, which can lead to overheating and damage.
