    that to me looks half decent. Its not a 90" turn with a sharp edge so it shouldn't creep a whole lot. The tune and your turbo will also affect it.

    What yours looks like is what im doing to mine with a 90" weld el

    Srt v2 uses a "tear drop" wastegate with smooth transition from manifold to wastegate, but it still creeps. Can anyone shed some light on this?

    My understanding is that method helps considerable especially for cars like the 8thgen where it is tough to get a good wastegate placement unless you have a super manifold like Vit's or use 2 wastegates to make sure all sides of the collector are covered, but this tear dropping doesn't fix the creep completely.
