Simple question if you wrap your arm in Header wrap would your arm disipate heat as well? Why do you think they build them out of alluminum the Weight? NO it's so it will disipate the heat. You not only wrap headers for the heat they throw off but what do you do to make a chimney draw better? You make sure it holds its' warmth. The problem with internet car knowledge is that if ONE guy does something that others think looks "Real Cool" everyone does it, they do no reserach themselves. Why not wrap your whole interior so you don't need to use the Air Conditioning anymore? Man some of your guys' ideas are so unbelievable. Thats why checker auto and Pep Boys have that section of bolt on garbage for the Rice Tuners. Also why is everyone one of you so affraid of admitting you own a Chrysler and stop putting all the Mercedes Benz stickers on your cars? I will challenge any one or group of you to discuss the design and building of the Crossfire but I will not let you say it is a Mercedes. I have owned Mercedes and not "entry" level ones, now I choose to drive a Chrysler Crossfire and I am not ashamed of it. Rather proud that I can do what I please.
