But you do pay for what you get and the Kooks are amazing headers.
he said bend over and take it in the ***!!! lol yeah kook's and QTP's are the creme of the crop of the header world... but not everyone can afford them, great quality from people's headers i've seen. Trending Topics

The following article from Burns Stainless should probably be stickied in the exhaust FAQ. Stainless and coated mild steel primaries are not created equal.

I've read a few posts about people's ceramic coating flaking off in places in as short as 6 months... Food for thought.
From http://www.burnsstainless.com/TechAr...s_article.html
...there are companies that coat headers with a thermal barrier, typically some type of ceramic formula, in order to keep the heat inside the exhaust system. Stainless steel performs this function without the need for add-ons because it has a much lower coefficient of thermal conductivity, thereby keeping more heat inside and transmitting it to the header outlet. Radiated heat is perhaps the most important reason to wrap or ceramic coat the headers to protect the car and the driver from excessive, fatiguing high temperatures.
Typical 1010 carbon (mild) steel conducts 219% more heat per foot than do the types of stainless steel we use in header fabrication. By contrast, quite a bit more heat stays inside the stainless header tubes and does not get passed into the surrounding air. By not allowing the contraction of the cooling gases as they flow down the tubes, more exhaust velocity is retained which promotes better scavenging at the collector. This retention of velocity increases the overall header efficiency.
