Selling a set of MAC long tube headers for the 05-09 Mustang GT. They were used for about 50,000 miles. Aside from normal surface rust they are in normally-used condition. Also included is a MAC off-road Prochamber, which is their version of an off-road h- or x-pipe. I am asking $250 shipped OBO. I will ship FedEx ground. I am located in Milwaukee WI and can also meet locally.
