External 38mm Wastegate

Stainless steel is used for valve and valve housing with a high temperature actuator diaphragm. 
Actuator spring gives consistent pressure at high temperatures, resists "Relaxing" at high temperatures. 

Available colour: black only.

CNC machined 10mm thick weld flanges. 
Colour anodized aluminium actuator housing. 

External wastegate is commonly used for regulating boost levels more precisely than internal wastegate in high power applications. 

Wastegate vents excess boost into the atmosphere creating that great external wastegate sound all the drift and drag cars have.
