Good advice! I tried a million things. They kept blowing. Solution? Solid piping.
Had a friend weld a vband with an oring right onto the turbo, then one piece piping to a single coupler before the turbo
So basically the piping can’t move at all, it’s held in place by the vband and can only flex at the coupler, sufficient to dampen any harmful vibrations, but rigid enough that it will never blow off again. And sure enough I haven’t seen any issues yet.
