The Tial Sport MVR might be the single most reliable wastegates on the market. This 44mm beauty is the top choice for expelling excess exhaust gases on big turbo applications. In addition to being reliable, the Tial Sport MVR is smaller than any other 44mm or 46mm wastegate out there.
The compact Tial wastegate is constructed from high temperature friendly NiCrFe alloy. That’s great news since external wastegates will see some incredibly hot temperatures, and reliable construction is a must.
