The AMC Javelin is a classic American muscle car that has captured the hearts of automotive enthusiasts. One of the most effective ways to enhance its performance is by upgrading the exhaust system. In this article, we will explore how replacing the stock exhaust with a high-performance system can boost your Javelin’s power by up to 20 horsepower for under $700.
Understanding Exhaust Systems
An exhaust system is crucial for the performance of any vehicle. It manages the expulsion of gases produced during combustion, ensuring that the engine runs efficiently. For the AMC Javelin, a well-designed exhaust system can significantly improve airflow, reduce back pressure, and enhance engine performance.
Benefits of Upgrading the Exhaust System
- Increased Horsepower: A performance exhaust can add up to 20 HP.
- Improved Sound: A new exhaust system can give your Javelin a more aggressive sound.
- Better Fuel Efficiency: Improved airflow can lead to better fuel economy.
- Enhanced Aesthetics: A polished exhaust can improve the look of your vehicle.
Types of Exhaust Systems for AMC Javelin
- Cat-Back Exhaust Systems: These replace the exhaust system from the catalytic converter back.
- Header-Back Exhaust Systems: These include headers and replace the entire exhaust system.
- Axle-Back Exhaust Systems: These replace the exhaust from the rear axle to the exhaust tips.
Cat-Back Exhaust Systems
Cat-back exhaust systems are popular among Javelin owners. They are relatively easy to install and provide significant performance gains. Many cat-back systems are designed to improve sound and aesthetics while boosting horsepower.
Header-Back Exhaust Systems
For those looking for maximum performance, header-back systems are the way to go. They replace the stock headers and provide the best airflow possible. However, these systems can be more expensive and may require professional installation.
Axle-Back Exhaust Systems
Axle-back systems are the most straightforward option. They are easier to install and focus on the rear part of the exhaust system. While they may not provide as much performance gain as cat-back or header-back systems, they are a cost-effective solution for improving sound and aesthetics.
