Used set of ATR style headers which I assume are Chinese. If I remember correctly they may be from SSautochrome. All of the tubes are stainless steel. The flanges that bolt to the heads are magnetic so they may not be stainless and also have a cast appearance (not perfectly smooth). I'm offering them as a project for someone who needs a set for mock up purposes, wants to experiment with welding their own and can learn on these, or just wants a cheap pair of headers that need some work. When they were on my car I noticed a small leak at the passenger side collector and at the connections between the pipes. The leaks at the connections were probably from using the cheap v-bands that they came with. A quality clamp may have cured the issue. I ran these headers for 4 years and made 538 rwhp with them, but decided to replace them when making a turbo swap. Asking $175 or best offer shipped within the U.S. The condition in the pictures is how they will be sent. Feel free to ask questions. Thanks.
