Product Description

The Perrin PSP-EXT-058 Equal Length Header is a high-performance exhaust upgrade designed for turbocharged Subaru vehicles equipped with FA24 or similar engines, including the WRX, Outback XT, Legacy XT, and Ascent. Crafted from durable 304 stainless steel with a brushed finish, this equal-length header replaces the restrictive stock manifold to promote smoother and more balanced exhaust flow. The larger primary and secondary tubes help reduce backpressure and support stronger exhaust pulse timing, which may contribute to improved turbo response and overall performance without sacrificing drivability.

Designed to integrate seamlessly with the vehicle's factory heat shield and exhaust components, the PSP-EXT-058 header maintains proper thermal management and is compatible with many stock and aftermarket up-pipes and turbo systems. No ECU retune is typically needed for basic bolt-on applications, but custom calibrations should be reviewed with your tuner. This header includes all necessary hardware and instructions, making it an excellent choice for enthusiasts looking to enhance exhaust flow, throttle response, and sound quality on their Subaru performance build.
