So i have this manifold but i need a wastegate for it and all the 40mm or 50mm i can find are knock off parts and from what i read about wastegates the cheap ones leak or fail and can cause engine damage.
what are some wastegates that will mount to this flange that are of high quality and durable/reliable?
