35-38mm External Wastega te Flange w/Drilled Hole

The 35-38mm External Wastegate Flange with Drilled Hole by VIBRANT PERFORMANCE is a precision-engineered component designed for turbocharged engine builders and performance tuners working with Deltagate, Tial, and Turbosmart wastegate systems. This flange serves as the critical mounting interface between the wastegate valve body and the exhaust manifold or custom exhaust piping, enabling proper boost control and pressure relief in forced-induction applications. Whether you're building a high-horsepower street engine, track car, or competition platform, a quality external wastegate flange is essential for reliable boost management and engine safety.

Manufactured from durable steel in a natural finish, this flange features a 0.375-inch thickness that provides structural rigidity and reliable sealing under high exhaust temperatures and pressure cycles. The pre-drilled hole accommodates standard fastener patterns for 35-38mm wastegate valve bores, ensuring proper alignment and leak-free installation without requiring custom drilling or fitment work. The flange design allows for both conventional manifold mounting and custom exhaust routing applications, making it adaptable to various turbo configurations and engine bay layouts where space or design constraints demand external waste gating solutions.

Performance builders and tuners rely on this component when constructing boost-control systems that demand precision engineering and repeatable quality. The compact footprint (5.95 x 6.95 inches) suits both tight engine bays and custom manifold fabrication projects, while the lightweight construction (0.36 lbs) minimizes added mass without compromising durability. This flange is compatible with Deltagate, Tial, and Turbosmart 35-38mm wastegate models, making it an ideal replacement or upgrade component for maintenance, repair, or custom build applications where OEM equivalents may be costly or unavailable.
