Im selling my stack kit. I have about 1200 into them. Its doesnt include the down pipe but does include the pipe from the down pipe back. So its basiclly the universal kit plus the pipe that goes from the down pipe back. It has never seen winter since I dont drive it. They have about 10k miles on them. The diamond plate cover has a few holes where I mounted the air tank and water pump.It has 6"x48 stacks.
