You can firm up the drivetrain by using a torque strap (it's unloaded at low/no-load) and/or using polyurethane mounts if the Metro's are shared with a performance-oriented vehicle (entire mounts or poly inserts), or fabricating stiffer mounts (e.g. if the mount has voids, filling it with urethane casting compound; let me know if you want more info on this).
It would probably be better to use a flex joint instead of a flex pipe. If you orient it near the rotation center of the drivetrain, it will have to flex/move less.
