GFB EX44 44 mm external wastegate — 7002
The EX44 is GFB’s compact 44 mm V-band external wastegate, designed to deliver strong flow in limited engine-bay space.
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 EX44 inlet and outlet flanges, spring configuration and the required boost-control range before installation.
