Vibrant external wastegate adapter flange in 304 stainless is built for 35–38mm Tial wastegates and offers a precision laser-cut fit for turbo manifolds. At 3/8 in thickness the flange resists heat warping and supports transitions between wastegate styles, including tapped bolt options. The flange uses a 70mm bolt circle and a roughly 36mm port ID for accurate external wastegate plumbing.
