The EX50 50mm wastegate has been designed to out perform all other similar size wastegates on the market. GFB uses stainless steel for the valve body and seat and 7075 aluminum on the actuator housing for strength and durability. It includes 3 springs that can be mixed and matched to produce boost levels of 7, 9, 13, 16, 20, 22 and 29psi. They constructed the gate to be as small and compact as possible while remaining as high flowing for rock solid boost control. The unit also includes the v-band mounting clamp as well as weld on flanges. It can also be used with any flange designed for the Tial 44mm when the included GFB adapter is used.
