GFB EX50 External Wastegate

GFB EX50 50 mm external wastegate — 7001

The EX50 is GFB’s compact 50 mm V-band external wastegate for high-flow turbo systems.

GFB uses a 253MA chromium-nickel stainless investment-cast body, a machined stainless valve, stainless weld-on hardware, a billet 6061 aluminium actuator housing and a Nomex-reinforced silicone diaphragm. An internal shroud helps protect the valve stem from heat and carbon build-up. V-band mounting; made in Australia under ISO 9001.

Confirm the EX50-specific inlet and outlet flange arrangement, available height, spring selection and boost-control strategy against your manifold and dump-pipe setup.
