I wanted to share an experience I had with Hedman regarding my coated headers. I bought the headers new about a year ago and they have developed some discoloration and rust pitting. this happened eventhough my car is far from complete and the only time on the motor is initial break-in, tuning time and some very short trips through the neighborhood. I called Hedman to explain what was going on and see what I could do. The first question I was asked was whether or not I used the headers during break-in. I told him I did and he said that is what caused the problem. Somehow, I managed to miss the warning to not use coated headers for engine break-in. To make a long story short, they offered to re-coat the headers for no charge (except shipping) because I was honest about my mistake and didn't try to BS them. It was a great experience with a happy outcome. Based on this, I wouldn't hesitate to recommend their products to anyone. Just thought I would pass along the info in case anyone else has a similar problem.
