Did you already throw out the bubble wrap they came in. I would have left it on the headers until you got them situated in the engine bay. It would keep them from getting dinged up a little. I just uncovered the flange, and left the bubble wrap on until I got them all bolted up. Then I just tore off the bubble wrap. Just a suggestion. I know you will love the sound. It was deffinatly worth it IMO. Good Luck
