Weird on the color under your car and trunk. My entire car is yellow, underside, trunk and all lol. I noticed on the 2011 GT 500 which is grey the underside and trunk are a greenish color too.
I feel your pain on the lines going by the exhaust. Still need to figure out something with my fuel lines. Not much space there to make it from trunk to front without getting near exhaust.
Yea it will not be good if my insulation burns....there just isnt alot of options.... maybe tack some sort of heat shield inbetween..... Kinda like the shield on motor cycles between the inside of the fairings and the bike.....
