The classic Dodge Charger has long been a symbol of American muscle, renowned for its powerful performance and iconic design. One of the most effective ways to enhance the performance of these classic vehicles is through the installation of Mopar performance headers. In this article, we will explore the benefits of Mopar performance headers, the installation process, and the potential power gains that can be achieved.
Understanding Mopar Performance Headers
Mopar performance headers are designed to improve exhaust flow from the engine, allowing for better performance and efficiency. These headers replace the factory exhaust manifolds, which can be restrictive and limit the engine’s power output. By using high-quality materials and advanced design techniques, Mopar headers can significantly enhance the performance of classic Chargers.
Benefits of Upgrading to Mopar Performance Headers
- Increased Horsepower: Headers can improve horsepower by enhancing exhaust flow.
- Better Torque: Improved exhaust scavenging can lead to increased torque across the RPM range.
- Improved Sound: Headers can give your Charger a more aggressive exhaust note.
- Enhanced Engine Efficiency: Better airflow can lead to improved fuel efficiency.
Installation Process of Mopar Performance Headers
Installing Mopar performance headers on a classic Charger can be a rewarding project for enthusiasts. While the process may require some mechanical knowledge, it can be accomplished with the right tools and preparation. Below is a step-by-step guide to help you through the installation process.
Tools and Materials Needed
- Socket set
- Wrench set
- Torque wrench
- Header gaskets
- New exhaust bolts
- Jack and jack stands
- Safety glasses and gloves
Step-by-Step Installation Guide
Follow these steps to install Mopar performance headers on your classic Charger:
- Step 1: Prepare the Vehicle – Begin by parking the Charger on a flat surface and engaging the parking brake. Use a jack to lift the front of the vehicle and secure it with jack stands.
- Step 2: Remove the Old Exhaust Manifolds – Disconnect the battery and remove any components obstructing access to the exhaust manifolds. Unbolt the old manifolds and carefully remove them from the engine.
- Step 3: Clean the Surface – Clean the mating surfaces on the engine to ensure a proper seal for the new header gaskets.
- Step 4: Install Header Gaskets – Place the new header gaskets onto the engine, aligning them with the bolt holes.
- Step 5: Position the Headers – Carefully position the Mopar performance headers onto the engine, ensuring that they fit correctly with the gaskets in place.
- Step 6: Bolt the Headers – Using new exhaust bolts, secure the headers to the engine. Be sure to follow the manufacturer’s torque specifications to avoid leaks.
- Step 7: Reinstall Components – Reattach any components that were removed during the process, including exhaust pipes and heat shields.
- Step 8: Reconnect the Battery – Once everything is back in place, reconnect the battery and check for any leaks.
Power Gains from Mopar Performance Headers
One of the primary reasons for installing Mopar performance headers is the significant power gains that can be achieved. While the exact increase in horsepower and torque will depend on various factors, including the engine setup and tuning, many enthusiasts report noticeable improvements after installation.
Expected Power Gains
On average, Mopar performance headers can provide the following power gains:
- Horsepower Increase: Expect gains of anywhere from 10 to 30 horsepower, depending on the engine configuration.
- Torque Increase: Torque can also see a boost, with gains typically ranging from 15 to 25 lb-ft.
- Improved Throttle Response: Many drivers notice a more responsive throttle after header installation.
Conclusion
Installing Mopar performance headers on a classic Charger is an excellent way to enhance its performance and driving experience. With increased horsepower, improved torque, and a more aggressive exhaust note, these headers can transform your classic muscle car into a true powerhouse. Whether you’re a seasoned mechanic or a novice enthusiast, the installation process can be a fulfilling project that yields significant rewards.
