The GFB EX38 External Wastegate has a inlet flange I.D. that 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.

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!

Directly compatible with TiAL MV-S/38mm flanges, meaning you can use the EX38 on turbocharger kits designed for TiAL wastegates.

Stands in at only 93mm tall and is shorter than its nearest competitor.
