Rear undertray look great! How close did you get to the exhaust? I see how you attached it on the contour of the bumper, but how did you attach it everywhere else?
Also you got pics of your WAI setup?
the tray is screwed on everywhere except the right front that has a flat panel screwed on and the bottom is zip tied to the front. I kept the plastic 4" from the exhaust. I'll be putting some thin gauge stainless on the exhaust side.
The HAI was a pain to route but I got it in there Air temps run 150-160f
