Insulating the engine bay

I had originally thought about running this up the exhaust column. I'd also planned on eliminating the muffler and jet coating the pipe(s). Any ideas on whether I should look for something with better heat abilities or other ??

John,

Do those ceramic coatings significantly lower the surface temps of the pipe? I'd be worried that 300 deg F isn't enough. I can see pipe temps easily hitting 1000 deg F. I'd be concerned that the insulation may work it's way lose from the chute walls and fall onto the pipe possibly causing a fire hazard. My '02 LXi was shipped from the factory with a muffler blanket that went completely around the muffler and along the full height of the muffler. It was a stout blanket with a thick skin and a fiber fill in the middle - definitely rated for the heat.
