The Subaru WRX has long been a favorite among car enthusiasts, known for its performance and rally heritage. One of the most effective ways to enhance the WRX’s performance is by upgrading the exhaust system, particularly with headers. In this article, we will review the Perrin WRX headers, focusing on the deep exhaust note they produce and the horsepower gains they offer.
What Are Headers?
Headers are an essential component of the exhaust system that replace the factory exhaust manifold. They are designed to improve the flow of exhaust gases from the engine, which can lead to increased horsepower and torque. By allowing exhaust gases to exit more freely, headers can enhance engine efficiency and performance.
Overview of Perrin WRX Headers
Perrin Performance is a well-known brand in the automotive aftermarket, particularly for Subaru models. Their WRX headers are crafted from high-quality materials and designed to provide significant performance improvements. Here’s what you can expect from Perrin WRX headers:
- High-grade stainless steel construction for durability
- Optimized design for improved exhaust flow
- Deep, aggressive exhaust note
- Increased horsepower and torque
Deep Exhaust Note
One of the standout features of the Perrin WRX headers is the deep exhaust note they produce. Unlike the factory exhaust system, which can be somewhat subdued, the Perrin headers provide a more aggressive sound that many enthusiasts crave. This deep tone not only enhances the driving experience but also gives the WRX a more sporty character.
The sound produced by the headers is a result of the improved exhaust flow and design. Many users report that the sound is not overly loud, making it suitable for daily driving, yet it provides a noticeable increase in volume when accelerating. This balance makes the Perrin headers a popular choice among WRX owners.
Increased Horsepower and Torque
In addition to the improved sound, Perrin WRX headers are engineered to increase horsepower and torque. By optimizing the exhaust flow, these headers can help the engine breathe better, leading to more power output. Many users have reported gains of 15 to 20 horsepower after installing the headers, which can significantly enhance the overall performance of the vehicle.
It is important to note that the actual gains may vary depending on other modifications made to the vehicle, such as tuning, intake upgrades, and exhaust systems. However, the Perrin headers are a solid foundation for anyone looking to boost their WRX’s performance.
Installation Process
Installing the Perrin WRX headers is a task that can be completed by those with moderate mechanical skills. Here is a brief overview of the installation process:
- Gather necessary tools: socket set, wrenches, and possibly a lift or jack stands.
- Remove the factory exhaust manifold and any associated components.
- Install the Perrin headers, ensuring a proper fit and seal.
- Reattach any components that were removed during the process.
- Start the engine and check for leaks or issues.
While the installation can be done at home, many choose to have it done professionally to ensure everything is fitted correctly. Proper installation is crucial for maximizing the benefits of the headers.
Conclusion
The Perrin WRX headers are an excellent upgrade for any Subaru WRX owner looking to enhance their vehicle’s performance and sound. With their deep exhaust note and potential for increased horsepower, they offer a compelling reason to consider an exhaust system upgrade. Whether you’re a daily driver or a performance enthusiast, these headers can significantly improve your WRX experience.
As always, it’s recommended to pair header upgrades with other modifications and a proper tune to fully realize the performance potential. If you’re looking to take your WRX to the next level, Perrin headers are a worthy investment.
