well it basically is a form of subframe so get it roon ye

anyway

the downpipe was hitting off the corner of the "kidney plate" as you call it, and thus wasnt allowing it to go forward enough to mate up with the turbo elbow!

problem = exhaust wasnt up on the mounts at the rear, as had it all in one piece under the car, so it was somehow stopping it from coming onto the turbo elbow at that angle, rectified by mounting the rubbers at the back - that help ure small brain
