I did not cement the carpets on the floor. The seats keep the main sections secured. The floor tunnel mats are secured with snaps. Floor mats will tend to slide around a bit and it helps to secure them in some fashion.

I ceramic coated my exhaust back to - but not including the tailpipes. I have a lot of insulation on the floor so it's not bad down there - but at stop lights the heat is going to well in over the top of the doors from the exhaust no matter what you do. My ceramic coated SpinTech mufflers read around 500 deg when I shut things down after a ride down the road. I'm not sure how much good the ceramic coating does.
