When i put an undertray under the back of my civic, i upset the airflow through the cabin as the exhaust vent is behind the rear bumper and must have required a negative pressure in that area to work. Installing the tray blocked off that area so i cut a little vent there and put in some flexi duct with no improvement. My windows fogged up constantly right up until i retired my civic. So i'll have to watch that when i undertray my yaris then......
