GFB EX50 External Wastegate Universal 50mm V-Band

GFB EX50 External Wastegate - Universal - 50mm V-Band

GFB has built a strong reputation among boost control specialists for combining serious flow capacity with compact packaging, and the EX50 continues that approach. Designed using CAD modelling to eliminate unnecessary bulk, this 50mm external wastegate is aimed at high powered turbo applications where reliable boost control under extreme heat is non-negotiable.

This listing covers the GFB EX50 External Wastegate, a universal fit 50mm V-band unit suited to a wide range of turbocharged builds, from circuit and drag applications through to high output street cars. It's supplied ready to fit with the included V-band hardware, making it a straightforward upgrade for custom exhaust manifold setups.

Note: The EX50 ships with a 13psi (90 kPa) spring fitted. Additional 7psi (48 kPa) and 9psi (62 kPa) springs are available separately and can be combined with the supplied spring to achieve boost pressures of 48, 62, 90, 110, 138, 152 and 200 kPa (7, 9, 13, 16, 20, 22 and 29psi).
