New TTI's rusting?????

OMG I am sick. The brand new TTI's I just installed last fall are rusting. The car doesn't have 5 miles on it yet and I used old headers to break the motor in. This shouldn't be happening should it? I need to contact John Cambridge...that's who I bought them from. Anyone know his email? I know he's a member here. Anybody else have this problem. I paid a king's ransom for these because I was told they were the best.
