I'm going twin turbo so the headers have got to go. They are Maximizer long tube headers. Made from 304 stainless. The fit on them is perfect. I put an extra fitting the collector for a wideband sensor. The kit come with the long tube headers, resonators, and mid pipes. I will try so save the gaskets on the collector and heads. I will throw them in. These are still on my car and I will take them off carefully when they sell. I'm asking $550 for the setup.
