Used Doug Thorley as well but the 1 7/8" mid length. Do not like the look of exhaust hanging under a frame. Required minor trimming on top rail. Can see them mounted in page 7 of my build thread. I am using the Pacific Fab crossmember. As noted in my post, there is minor interference with passenger side shackle bolt. Probably could be rectified by trimming bolt.
