Thank you very much for this DIY
I did this using your DIY.
I have very limited experience of this type of jobs, but it went well.
Total work time 4+4+2 hours.
4h first install. (The right downpipe was rubbing against the frame of the car.)
4h attempt to make clearance between the DP and the frame of the car.
2 h second attempt. Success.
