TIAL MV-R Wastegate 

The MV-R 44mm wastegate is more compact than any current 44mm or 46mm wastegate on the market. You get two top and three bottom air ports for an easy install. This unit is a direct bolt-on for our V44. The MV-R also has an optional extreme high temp casting available for Motorsport applications.
