With additional 5 psi, 7 psi and 10 psi springs, different combinations can be used to set a base boost pressure of 5, 7, 10, 12, 15, 17 or 22 psi*.<\/p>\n<p>At just 93 mm high, the EX38 is shorter than the closest competing products. The internal diameter of the inlet flange has a tapered inlet, helping provide a smoother transition from the exhaust pipe into the valve, while the internal seat diameter is larger than that of other wastegates of the same size, allowing greater flow.<\/p>\n<p>The EX38 is directly compatible with TiAl MV-S flanges, so it can be used on turbo kits designed for TiAl wastegates.<\/p>\n<p>With external wastegates, both high flow and compact dimensions are important. GFB offers one of the most compact ranges of external wastegates in its class \u2013 with a lower height than the closest competing products and no reduction in flow.<\/p>\n<p>All GFB wastegates feature a cast housing made from 253MA chrome-nickel stainless steel, a CNC-machined solid stainless steel valve, and fully stainless steel weld-on connections and mounting hardware.
