The Mazda Miata is a beloved sports car known for its lightweight design and exceptional handling. One of the most effective ways to enhance its performance is by upgrading to high-quality headers. AP Racing headers have gained popularity among Miata enthusiasts for their ability to improve engine efficiency and power output. In this article, we will explore the performance gains achieved with AP Racing headers on the Miata, supported by real results and dyno charts.
Understanding Headers and Their Importance
Headers are an essential component of an engine’s exhaust system. They are designed to optimize the flow of exhaust gases from the engine to the exhaust system, reducing back pressure and improving overall performance. By replacing the stock headers with aftermarket options like those from AP Racing, Miata owners can experience significant gains in horsepower and torque.
Performance Gains from AP Racing Headers
AP Racing headers are engineered to provide several performance benefits. These include:
- Increased Horsepower: AP Racing headers can lead to noticeable increases in horsepower, often ranging from 10 to 20 additional horsepower depending on the specific Miata model and engine setup.
- Improved Torque: Alongside horsepower gains, torque improvements are also common, enhancing the vehicle’s responsiveness and acceleration.
- Better Throttle Response: The design of AP Racing headers allows for quicker exhaust gas evacuation, resulting in improved throttle response.
- Enhanced Sound: Many enthusiasts appreciate the deeper, more aggressive sound that comes with aftermarket headers.
Real Results: Dyno Testing
To validate the performance gains from AP Racing headers, dyno testing is essential. Below, we present dyno charts comparing stock headers to AP Racing headers on a Miata.
