What is the point of 180 degree headers? They seem to me to be a way to use your engine bay as a heat exchanger, basically you use your engine and bay as a giant heat sink, attempting to prevent all possible heat loss to the outside world. Is the 180 degree part the temperature of everything under the rear lid when they are installed?
Kidding.
Anyway, what is the advantage, I gather there is a performance advantage but I'm not sure what the "180" part gets you. Isn't running the exhaust down and out with large-bore long-tube headers with minimally restrictive mufflers accomplishing the same thing?
Educate me.
As an aside, I have just had my original ANSA units blasted and coated so they are going to be around for awhile. Is there a header upgrade I can use with my original heads and exhaust? Thanks.
