The GFB EX38 is a high-quality 38 mm external wastegate that combines maximum flow, compact dimensions and extreme reliability. At only 93 mm high, it is more compact than many competitors, but thanks to the tapered inlet flange and a larger seat diameter actually provides more flow. The wastegate comes standard with a 10 psi spring, and can be adjusted with optional springs between 5 and 22 psi.
The EX38 is fully compatible with TiAl MV-S Flanges make it easy to install on existing turbo setups. The construction consists of high-temperature stainless steel with a durable Nomex-reinforced silicone diaphragm. The V-band mounting ensures a quick, secure, and leak-free fit.
Manufactured in Australia under ISO 9001 quality standards for maximum reliability. A perfect upgrade for those who need high boost stability and optimal flow in street, track, or racing applications.
