A high-flow 10.5cm turbine housing for the 2015-2021 Subaru WRX STI (VA) 2.5L Turbo, replacing the restrictive factory 7cm housing to cut exhaust backpressure and free up top-end power.
The AMR Performance 10.5cm Turbine Housing is a high-flow exhaust housing upgrade developed for the 2015-2021 Subaru WRX STI (VA) equipped with the factory-style turbocharger.
Replacing the restrictive factory 7cm turbine housing with AMR’s larger 10.5cm housing increases turbine-side flow capacity, reduces exhaust backpressure, and allows the turbocharger to operate more efficiently at higher engine speeds and boost levels.
The larger 10.5cm design is especially beneficial for modified vehicles where the factory housing becomes a restriction. By improving exhaust flow through the turbine, the AMR housing helps support stronger top-end performance and provides additional airflow headroom for higher-output turbocharger combinations.
Designed as a performance upgrade rather than simply a replacement housing, it offers an effective way to improve the turbine side of a factory-style Subaru turbo without requiring an entirely different turbocharger configuration.
Key benefits: upgrades the factory 7cm housing to 10.5cm; increased turbine-side exhaust flow; reduced exhaust backpressure at higher airflow levels; improved high-RPM efficiency and power potential; greater headroom for increased boost and airflow; ideal for upgraded and hybrid factory-style turbochargers; designed for the 2015-2021 Subaru WRX STI VA 2.5L Turbo.
For Subaru STI owners pushing beyond the limitations of the factory turbine housing, the AMR Performance 10.5cm Turbine Housing provides the additional flow capacity needed to let the turbocharger breathe and continue making power where the smaller factory 7cm housing begins to become a restriction.
