- Design: The headers feature a smooth, mandrel-bent design that minimizes restrictions in exhaust flow.
- Fitment: Designed specifically for the WRX, Perrin headers offer a precise fit without the need for modifications.
- Heat Resistance: The headers are engineered to withstand high temperatures, maintaining performance even under extreme conditions.
Benefits of Upgrading to Perrin Headers
Upgrading to Perrin WRX headers comes with several advantages that can enhance your driving experience:
- Increased Horsepower: Dyno tests have shown that Perrin headers can provide significant horsepower gains, often exceeding 15-20 whp.
- Improved Torque: Alongside horsepower, torque improvements are also observed, contributing to better acceleration.
- Enhanced Exhaust Note: The headers produce a more aggressive and rugged sound, enhancing the overall driving experience.
- Better Throttle Response: Improved exhaust flow leads to quicker throttle response, making the car feel more responsive.
Dyno-Verified Performance Gains
Perrin headers have undergone extensive testing to validate their performance claims. Dyno charts reveal impressive gains in both horsepower and torque across various RPM ranges. For WRX owners, these verified improvements translate to a more exhilarating driving experience.
Dyno Testing Results
In controlled dyno testing, vehicles equipped with Perrin headers demonstrated:
