DNA Motoring 38mm External Wastegate - Turbo Manifold Boost Controller With 14 PSI Spring

Turbo builders, this DNA Motoring external wastegate is serious business for controlling your boost levels!

The 38mm stainless steel valve fits any standard 2-bolt wastegate port and works by bypassing exhaust flow from the turbine wheel to regulate boost pressure.

The high-strength cast body features anodized aluminum top finish and comes with weldable flange inlets and outlets for custom installation.

Includes a 14 PSI spring right out of the box, and the easy-to-remove locking collar makes spring changes quick when you want to adjust your boost levels.

Barbed fittings are included for your boost reference lines.

The stainless steel sealing ring ensures no exhaust leaks, while the external design allows bypassed flow to be reintroduced further downstream in your exhaust system - which actually improves turbine performance compared to internal wastegates.

Perfect for custom turbo setups where precise boost control is critical.

Whether you're building a performance street car, track machine, or anything in between, this wastegate gives you the reliability and adjustability you need.

Mounts directly to your exhaust manifold or header.

Get your boost under control with this quality external wastegate that can handle whatever your turbo setup can throw at it!
