Jeff,
Some good suggestions above. There is a local alternative if you are interested. Take a look at Accessories Plus in Belmont (ask for Steve). They ceramic coated the entire exhaust system for my FIA. You can do all the test fitting and tweaking to get everything to hang properly and fit just right on your 427, then take it in for ceramic coating.
Your set up will be different that mine, but below are some photos of the coating for my partial under car set up. They did a great job and I am very pleased with the end result.
