You don't actually need the brackets, the N54 guys have been running bracketless downpipes since 2007 without any issues with cracked turbo manifolds.
We just received our new F10 535i DP's, similar design without the brackets except ours is polished and a couple hundred bucks cheaper
We've had nothing but praise from our test cars
