Looking for GT40 MK1 289/302 Exhaust, prefer located in US due to cost of shipping but will consider others. I’m mating to a 986 transaxle so any Audi based or similar design should work. New/good shape used in either 1 5/8- 1 3/4” & with/without mufflers doesn’t matter as I’m building a custom/scratch build and can modify as needed.
