These are true MSP manifolds but because of Mike's high standards these didn't meet them and he refused to sell them under the MSP name. They have a pin holes that can't be seen with the naked eye in the gasket area so they DO NOT LEAK what so ever. I purchased these from Specialty Z at a discount because of it.
I'm just feeling the market out since they've become unobtainable. Email me your best bid if you want them and if the price is right I'll let them go.
