Buzz- that was stunningly perceptive of you.
I have run my pipes both ways and have been able to document that they are indeed faster when coated or painted black. According to my studies, black pipes ( I say pipes because I have found that the results also hold true for the pipes in my GT40 - rear pipes if you will....) are consistently three and a quarter thousandths of a second faster to 60 than silver or chrome pipes.
Methodology: I had my significant other stand at the side of the road in front of my house with a digital stopwatch and she would start the timer when I dropped my hand and then stop it when I raised my hand. We did this test 20 times each time I got a new car and the results were conclusive.
