Awesome! They are one good looking hitch. I put my Stealth on a few weeks ago. This walkthrough from nigelvh is what I followed. It does a good job of explaing everything.
I unbolted the muffler and then just let if hang by the outside hanger, being a brand new car it was easier to do that and have it out of the way.
Also, I broke one of the plastic tabs on the bumper, it was a little chilly out and even though I had the heat on in the garage the bumper wasn't as flexible as it probably should have been. I'd try to work in a warm place and let your car warm up if that's an option for you.
