The GFB 44mm V‑band external wastegate is a compact, high‑temperature discharge valve for boosted engines. It uses an investment‑cast 253MA chromium‑nickel stainless steel body, a one‑piece stainless valve and a Nomex‑reinforced diaphragm to withstand extreme exhaust conditions. Supplied with 5psi and 10psi springs and an optional 7psi spring; springs may be combined for base boost settings from 5 to 22psi. CNC‑machined internals, an internal shroud protecting the valve stem, V‑band clamp mounting and Australian ISO 9001 manufacture back its construction.
