TiAL MVS Wastegate - 38mm V-Band External Wastegate by TiAL Sport

The MV-S 38mm unit is much more compact than its F38 predecessor - standing only 3.7" in height. The V-Band flanges make installation pain free, the three lower & two upper air ports make connecting pressure sources and boost controllers easy!
