The Forced Performance HD7582 S400X street turbo with a T4 divided 1.25 A/R turbine housing increases exhaust capacity for larger-powered street builds. The larger A/R helps extend top-end flow while the T4 flange preserves compatibility with many manifolds and plumbing setups. It’s a practical choice for fabricators and engine upgraders seeking S400X flow in a street-oriented package.
