I have had two different sets of headers on my car now, Mac first they were on a week and rusted out, they got taken off immedieatly, then i put the bbk chrome ones on there, the turned a bit blue around the collector and at the port, but otherwise not too bad. But the temps underneath the hood are rediculous. I was gonna wrap the bbk's but I thought that would look ugly, so I wanted to know if that coating really worked as advertised.
