Speed tip: Black sidepipes are definitely faster! - Page 2

My experience also says black side pipes are faster. That's because my muffled street pipes are shiny ceramic, but my straight-through track pipes are BBQ grill black. I think the forward thrust of all that noise exiting out the straight pipes at full throttle must be good for at least two or three MPH. The only time they seemed slower was when I had to back off the throttle passing the microphone used to identify cars exceeding the track's noise limit.

That's just the info I needed to push me over the edge.

Brushed arruminum and black paint...nothing else matters.

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.
