This is a MAC Off-Road H-Pipe, part # 438690. It was ceramic coated by Jet-Hot. It was installed, and the car was started to check for leaks. It was never driven. The car has been sitting since then, so the h-pipe has 0 miles on it. It has been on the car for a couple of years now. The h-pipe is a 2-piece design. There is a left half and right half. It fits 1979-1993 5.0 Mustang. Price:$150.00, plus shipping. Thanks.
