Default how to reduce stress cracks on twin mid mount setup

Hey guys, I will be running twin turbos on my s10. The plan is to run turbos bolted to custom 1/4"brackets welded to the frame under the cab to support the weight. From the headers to the turbos will be 2.5" ss piping. How can I reduce the risk of stress cracks in the piping/welds due to engine/trans moving? I am running Current's poly mounts and poly trans mount.

use flex joints in between the headers and turbos. The motor shouldnt move much with the poly mount. I have a single turbo mounted to the frame, with poly engine mounts, flex joints and havent had any issues.

I don't think the motor would move much with poly mounts. Flex joints will hold up to the boost with no problem?

Yes, I think vibrant performance is where i got mine from. The flex joint for turbo applications has an interlocking line on the inside.
