I have a used down pipe and header, both the header and the down pipe are stainless steal and I do not know the brand. I bought the car used and the items were on the car but I preferred stock. The car had 25k miles on it when the headers and pipe were taken off but I am not sure how long they have been on the car before that. I have the hardware for the items that was taken off the header and down pipe also. Hopefully someone can get some good use out of them! Email me if you are interested or have any further questions! Thank you!
