engine under tray

[rxm6]

Pulled my engine undertray off because it was in pretty bad shape and dragging on the ground, but I don't want to leave it off. Is there anything better to replace it with, perhaps a metal piece or even another OEM tray?? I just don't think I should drive it without one on there. I did some searching, but I didn't really come up with anything, maybe I'm not naming it correctly.
