About Stainless Bros Vehicle / Engine Flange

Stainless Bros vehicle- and engine-specific flanges give fabricators a precise starting point for custom headers, manifolds, downpipes and exhaust systems. The flange pattern is matched to the listed engine or application while the tube opening, material and optional sensor/NPT provisions determine how the fabricated runners attach. These pieces reduce the need to machine a flange from raw plate, but the exact port shape, tube size and application still need to match the project. Confirm engine generation and tube diameter before welding components permanently.

Fabrication Note: Confirm material grade, tubing size, wall thickness, connection style and all listed dimensions before cutting or welding. Custom-fabrication components are generally not vehicle-specific unless an exact engine, turbocharger or sensor application is stated in the product details.
