The Subaru WRX is known for its impressive performance and distinctive sound. One of the key components that can enhance both aspects is the use of equal length headers. In this article, we will explore the benefits of Perrin Equal Length WRX Headers and how they contribute to a balanced sound and improved performance.
What Are Equal Length Headers?
Equal length headers are exhaust manifolds designed to ensure that each exhaust pipe is the same length. This design minimizes exhaust pulse interference, leading to better engine performance and a more harmonious sound.
Benefits of Perrin Equal Length WRX Headers
- Improved Performance: Equal length headers optimize exhaust flow, enhancing engine efficiency and power output.
- Balanced Sound: They produce a smoother and more refined exhaust note compared to unequal length headers.
- Enhanced Turbo Response: Better exhaust flow can lead to quicker turbo spool times, improving overall throttle response.
- Durable Construction: Perrin headers are built from high-quality materials, ensuring longevity and resistance to heat and corrosion.
Installation Process
Installing Perrin Equal Length WRX Headers requires a moderate level of mechanical skill. Here’s a general overview of the installation process:
- Gather Tools: Ensure you have the necessary tools, including wrenches, sockets, and a torque wrench.
- Remove the Old Headers: Disconnect the battery, remove the intake system, and unbolt the existing headers.
- Install New Headers: Position the Perrin headers in place and secure them using new gaskets and bolts.
- Reconnect Components: Reinstall the intake system and reconnect the battery.
- Test Drive: Start the engine and take the vehicle for a test drive to ensure everything is functioning correctly.
Performance Improvements
Many WRX owners report noticeable improvements after installing Perrin Equal Length Headers. These enhancements include:
- Increased Horsepower: Users often experience a boost in horsepower, particularly in the mid to high RPM ranges.
- Better Torque Delivery: Equal length headers can improve torque delivery, making the car feel more responsive.
- Enhanced Throttle Response: The improved exhaust flow leads to quicker throttle response, making the driving experience more engaging.
Sound Characteristics
The sound produced by Perrin Equal Length Headers is one of their most appealing features. Here’s what you can expect:
- Deep Tone: The headers create a deeper, more aggressive exhaust note compared to stock headers.
- Less Raspy: Equal length headers reduce the raspy sound often associated with unequal length designs.
- Consistent Sound: The sound is more consistent across the RPM range, providing a more enjoyable driving experience.
Considerations Before Installation
Before installing Perrin Equal Length WRX Headers, consider the following:
- Emissions Compliance: Check local regulations regarding emissions, as headers may affect compliance.
- Warranty Implications: Modifications may void certain warranties, so review your vehicle’s warranty policy.
- Professional Installation: If unsure about the installation process, consider hiring a professional for the best results.
Conclusion
Perrin Equal Length WRX Headers are an excellent upgrade for Subaru enthusiasts seeking improved performance and a balanced exhaust sound. With their durable construction and performance benefits, these headers can significantly enhance the driving experience. Whether you’re a casual driver or a performance enthusiast, these headers are worth considering for your WRX.
