2022-2026 Subaru WRX FA24F Equal Length Twin-Scroll Header

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.

• Configuration: Equal-length twin-scroll turbo header
• Tubing size: 1.75" OD runners maintained throughout the manifold
• Construction: Lightweight 16-gauge tubing designed to weigh less than OEM and competing headers
• Material options: Fully TIG-welded 304 stainless steel or mild steel
• Fitment: 2022-2026 WRX equipped with the FA24F twin-scroll turbo engine
• Design focus: Improved pulse balance, turbo response, flow efficiency, and reduced manifold weight
• Fabrication: CNC-cut flanges, hand-fabricated runners, and back-purged welds
• Sensor ports: No O2 bungs

Build time: Approximately 10-16 weeks depending on current production volume. Every header is hand-built in Deer Island, Oregon.
