This is the 1st gen Prius tray.

I did this about a month ago....

Compare to the Prius undertray in this article: Autospeed article: adding a chin undertray to a 1st gen Prius

At least we are on the same page.

Yesterday I kicked it up a notch.....

Prius Rear Undertray Rear View. The drivers side does come with a tray (diffuser) but the passenger side is open due to the complication of the muffler and exhaust. I used a screw thru the coroplast about 1" long that rests on the muffler to keep a gap between the coroplast and the muffler. From the rear, the white coroplast was quite visible. The green paint was all I had. I also ran out of coroplast. Once I get more I will do something less piecemeal and paint it black. I have yet to go for a drive. Hopefully nothing falls off.
