S/S Header Reducers - 3in to 2-1/2in

The Hedman S/S Header Reducers 3in to 2-1/2in (model 22115) is a precision engineered collector reducer designed for custom exhaust system fabrication in high-performance applications. Whether you're building a street rod, performance truck, or race vehicle, this reducer transitions from a 3-inch inlet diameter down to a 2.5-inch outlet, allowing seamless integration between larger primary tubes and smaller piping or muffler assemblies. This component is essential for builders who demand clean flow paths and proper backpressure management in custom exhaust configurations.

Constructed from durable steel in natural finish, the S/S Header Reducers features a 3-bolt ball and socket flange design that provides structural rigidity while accommodating slight angular misalignment during installation—critical in custom fabrication where perfect alignment isn't always achievable. The ball and socket flange allows for up to 15 degrees of deflection, reducing stress on connection points and welded joints. All necessary hardware is included, eliminating the need for sourcing additional fasteners. The smooth internal transition geometry minimizes turbulence and maintains exhaust velocity, contributing to optimal scavenging and engine performance across the RPM band.

Custom exhaust builders, automotive technicians, and performance enthusiasts will appreciate the versatility of this reducer in multi-tube collector applications. The pair configuration (sold as two units) accommodates dual-bank or split-tube systems common in V-block engines. Installation requires basic welding and flanged connection experience; ensure proper alignment before final welding to prevent exhaust leaks. The natural steel finish is compatible with ceramic coating, chrome plating, or powder coating if aesthetic matching is required in visible applications.
