I have a set of D453 ceramic coated headers for sale. Used for about 1000 miles. Never polished the coating so it is original thickness. Shipping is expensive. My zip is 59715.
Let me know. I'm planing on listing them for sale soon.
Just picked up a set from autozone.com ,they had 20% off shipped to home with free shipping ,brought them down to $476. that's as cheap as I have been able to find them. The 20 off ended the 28th but they regularly have 15% off if you are in no hurry to purchase them, wait for the sale and pick them up.
