The problem isnt where the dp connects to the catback. I problem is where the downpipe mount is. With the mount in the position it is in, even with the dp pulled down and driverside as possible there is only 1/4 in clearance between the dp and the transmission crossmember. So when under load in reverse or starting and stopping the enmgine, the dp wiggles a little and hits the transmission crossmember, I could put a little flat spot in the dp and solve the problem. I installed it by snugging the turbo bolts first (as I dont want any exhaust leak at the turbo), then the dp to catback bolts then the mount, then tightened everything. This caused loud rattles all the time, so i loosened the mount and pulled the dp and catback down while tightening the mount bolt. This solved about 90% of the rattles.
