2022+ Subaru WRX FA24 Stock Replacement Manifold

This manifold carries exhaust from the FA24 cylinder heads into the stock-location turbo. Its larger 1⅞-inch runners and cast twin-scroll collector give the exhaust a less restrictive path while retaining the factory turbo position.

I'd consider it for a tuned VB WRX, especially with an upgraded stock-location turbo, when the original manifold becomes a flow limitation. Slip joints accommodate heat expansion and help installation. ETS lists this manifold as requiring no tune by itself; changes to the turbo or boost still need their own calibration.
