EX38 External Wastegate

Compact. High-Flow. Built to Perform.

The GFB EX38 features a 38mm valve and comes standard with a 10psi spring, with additional springs available to achieve boost pressures from 5psi to 22psi.

At just 93mm tall, it’s shorter than its rivals while maintaining superior flow, thanks to a tapered inlet flange and a larger seat I.D.. The EX38 is fully compatible with TiAl MV-S flanges, making it an easy upgrade for turbo kits.

Crafted from high-temp stainless steel with a Nomex-reinforced silicone diaphragm, it’s built to withstand extreme conditions. The V-band mounting system ensures a secure, hassle-free installation.

Proudly made in Australia under ISO 9001 standards, the EX38 delivers reliability and performance in a compact package.
