Hoypeyfiy Turbo Exhaust Manifold External Black 38MM, Pressure Relief Valve Wastegate dump pipe valve Replacement for TIAL MVS Black With V-band And Flanges MV-S

Works as it should..Very strong quality,worth every penny .

Works great. Only comes with one spring. Mine holds 13 pounds of boost great. Will be testing 25 pounds once my boost regulator shows up. Easy to assemble but the cheap vband clamps they provide kinda suck. But they got the job done. Couldn't ask for anything better for the cheap price point. Very satisfied with this item.

Great but clamps not well fited

Good quality wastegate. Regulates boost just fine

Works well, however within 1000 miles the valve shaft o-ring failed, it would overboost then come back down, leading to poor boost control. I replace the o-ring with a universal one I had from a kit and it's working well again. I tested it on a bench with a regulator to find the leak, for example, the air rushed mostly past that seal and out the dump pipe, target spring was 7 psi, it took 10-11 psi for the air to overcome the leak and crack the gate, then it would instantly full open, reduce the pressure below 5 psi and it would open and fully leak again.

Diy'er quality. If you're looking for show quality piece, this isnt it, ***BUT*** it is outstanding for someone doing a turbo'd LS swap on a budget. Machining finishes could be better, but not terrible. The valve seat is finished nicely, and the correct material is used for the diaphragm. V-band flanges and hardware are quite good, and graded hardware is included, which is nice as other manufacturers provide cheapo hardware. Will absolutely use it again on another turbo system!

The wastegate blew up a couple days after putting it on my car. Seller would not let me return it to get a refund
