Vibrant 35-38mm External WG Flange Untapped Hole Tial/Turbonetic/Turbosmart Mild Steel 3/8in Thick

If you're building a custom turbo manifold and need to add an external wastegate, this flange from Vibrant Performance is a solid choice. It's specifically made to fit wastegates designed for 35-38mm ports, like those from Tial, Turbonetics, and Turbosmart. This means you get a clean setup without having to guess at port sizes or bolt patterns.

This flange is cut from 3/8-inch thick mild steel, giving it plenty of material to handle the heat and pressure of exhaust gases. The bolt holes are untapped, so you can thread them directly into your manifold or use separate nuts and bolts, depending on your fabrication method. Vibrant uses precision laser-cutting or CNC machining to ensure the flange mates up well to your manifold and the wastegate itself.
