EX38 - 38mm V-Band Style External Wastegate
The EX38 features a 38mm valve and comes standard with a 10psi spring. Additional springs are also available - by using various combinations of 5psi, 7psi, and 10psi springs, you can achieve base boost pressures of 5, 7, 10, 12, 15, 17, and 22psi*.
Standing only 93mm tall, the EX38 is shorter than its nearest rival. The inlet flange I.D. features a tapered entry to assist a smooth transition from the exhaust pipe into the valve, and the seat I.D. is larger than other wastegates of the same size for extra flow.
The EX38 is directly compatible with TiAl MV-S flanges, meaning you can use the EX38 on turbo kits designed for TiAl wastegates
When it comes to external wastegates, some things you want big, others you want small – like big flow, small size, right? GFB offers a range that are among the most compact external wastegates in their class, being shorter in height than their closest rivals without sacrificing flow.
All GFB wastegates feature an investment cast body made from 253MA chromium-nickel stainless steel, a CNC machined billet stainless valve, and all stainless steel weld-on fittings and hardware, whilst the diaphragm is nomex-reinforced silicone. All this adds up to a wastegate built to handle extreme conditions with reliability you can trust!
