Review PERRIN PERFORMANCE Subaru And Equal Length Headers fits WRX STI 2004–2020
Perrin Performance's PERPSP-EXT-055 Equal Length Headers for 2002-2014 Subaru WRX and 2004-2020 Subaru STI are a must-have upgrade for any performance-minded Subaru enthusiast. These headers are designed and engineered to provide significant power gains and improved throttle response, while also enhancing the overall sound and aesthetics of your vehicle.
The PERPSP-EXT-055 Equal Length Headers are made from high-quality 304 stainless steel, ensuring durability and longevity. The equal length design reduces exhaust backpressure, allowing for more efficient exhaust flow and improved engine performance. This results in increased horsepower and torque, as well as improved fuel efficiency.
One of the standout features of these headers is their unique 3-into-1 design. This design allows for optimal exhaust scavenging, reducing the amount of exhaust gases that are trapped in the cylinders during the combustion cycle. This results in a more complete and efficient combustion process, which in turn leads to increased power and improved engine efficiency.
Another feature of these headers is their 1.75-inch primary tubing and 3-inch collector. This combination provides a balance between power and sound, offering a deep and aggressive exhaust note without being overly loud. The headers also feature dual-electronic sensors for OBD-II compatibility, ensuring that your vehicle's check engine light will not be triggered.
Installing the PERPSP-EXT-055 Equal Length Headers is a straightforward process that can be completed by a skilled DIYer or a professional mechanic. The headers come with all necessary hardware, including gaskets, bolts, and studs, and are designed to fit seamlessly into your Subaru's exhaust system.

Whether you're a weekend warrior or a serious track day competitor, these headers are a great investment that will take your Subaru's performance to the next level.
