The Stainless Bros turbine outlet flange is designed to fit BorgWarner EFR S400-series T4 housings (S/SX/SX-E) and accepts 4-inch T4 turbine outlets. Machined from SS304 stainless steel, it provides the correct bolt pattern and outlet geometry to mate those EFR housings to 4-inch downstream piping, simplifying integration of EFR turbos into larger exhaust or downpipe systems.
