Lightweight equal-length performance for the FA24F platform. Designed specifically for the VB WRX, this twin-scroll equal-length header delivers balanced exhaust pulse timing to maximize turbine efficiency, improve turbo response, and support smooth high-RPM flow characteristics while reducing overall manifold weight compared to OEM and many aftermarket alternatives.
Unlike oversized heavy-wall manifolds, this design uses lightweight 16-gauge construction with consistent 1.75" OD runners maintained throughout the entire header into the collector. The result is excellent exhaust velocity, responsive boost characteristics, and a clean motorsport-inspired exhaust tone without excessive weight hanging from the turbo system.
