Perrin Equal-Length Headers for WRX and STI

Enhance your Subaru WRX or STI's performance with Perrin's premium equal-length headers. Designed for the 2002-2014 WRX and 2004-2020 STI models, these headers are engineered to deliver a smooth, powerful exhaust note while increasing horsepower. Unlike standard headers that compromise exhaust flow due to space constraints, Perrin's equal-length headers ensure optimal performance and efficiency.

Key Features and Specifications

The equal-length design of these headers provides superior exhaust flow, maximizing power output. While the boxer sound will be replaced with a more aggressive tone, the performance gains are undeniable. It's important to note that the equal-length header is not compatible with the stock EJ20 (2.0 liter) oil pan, requiring an EJ25 (2.5 liter) oil pan for installation. Additionally, the unequal-length header fits both oil pans and offers a versatile solution for various Subaru models. A comprehensive fitment guide is provided to ensure compatibility with your specific vehicle.

Practical Uses and Benefits

Perrin's equal-length headers are not just a performance upgrade; they are a practical solution for enthusiasts seeking to enhance their Subaru's driving experience. By installing these headers, you can expect improved acceleration, increased power, and a more responsive engine. To further optimize your setup, we recommend installing an Invidia up pipe at the same time. Don't forget to protect your investment with our exhaust wrap kit and Mach V EJ Header Heat Shield. Whether you're looking to compete on the track or simply want to enjoy a more dynamic driving experience, Perrin's equal-length headers are the perfect choice for your Subaru WRX or STI.
