Been following your posts, and also went with the Cool It Suppressor on our 2012 Lexi. Newer doghouse with a one piece oe shield that popped right out. Bought the 60" x 36" and suprisingly had a piece 27" x 36" left over. Looks to be just enough to cover driver and passenger floor area.
First pic is the Cool It installed, second is with gasket and oe shield back in place over the Cool It.
