This is essentally the exact same issue that the ecoboost gen 3s have been dealing with since day 1. The spring replacement is typically for 2021-early 2022 builds. Mine is a mid 2022 and that spring replacement did not apply to me, I had to have the entire exhaust replaced. The new exhaust has been fine since, which confuses me why R's are having this issue. My guess would be that the exhausts were ordered before the fix was implemented, and as such, the broken/dated parts were sent out the door.
