38mm External Waste-gate

The 38mm Waste-gate is a great addition to many OEM, modified, or DIY "garage build" turbo systems. Our precision-machined stainless steel valve and high-temp diaphragm allows for reliable use in both daily-driven street applications and weekend track days. The External Waste-gate is an integral part of a turbo system; it releases the exhaust to bypass the turbocharger to maintain stable boost pressure throughout the RPM range. In most OEM systems the internal style waste-gate is limited and can even be restrictive especially in performance applications, allowing undesirable inconsistencies and tuning issues. Adaption of an external Waste-gate to replace the internal style found in most OEM forced induction systems, presents an opportunity to increase boost pressure by providing the proper exhaust flow needed to reduce "boost creep" and/or "turbo surge."  Kit Includes Part Number: GN-TWG-038 ​- (1) 38mm External Turbo Waste-gate - (1) Installation hardware kit Specifications ​- 38mm wa
