I changed a couple on 405's previously

, I know what you mean, they come as a trombone shape to be straightened out and bent as appropriate.
I actually asked them to change them nearly two years ago, there was a bit of dampness at the rear end of the metal pipes, although they cut a few inches of metal pipe off and replaced the rubber feed / return hoses to the tank to suit. Did not charge me for this actually so I could not complain but I would of rathered they had changed them at that time. Not to worry.
I know they are nice and thick

, I have to keep reminding myself they are 20 years old though, (and they are damp in the middle!, since a couple of days ago)
The only area of concern really is the bypass hose (I had the fuel heater on the back of the block, the annoying 'I like to take in air' one) , bypassed this as I have one elsewhere now that I made but you have to ensure the rubber connection pipe between the front end of the main pipe to the one across the bulk head is tight or it will sit too close to the turbo. To be fair its further away than the original one, but if someone just fitted a length and did not look it could be too close or worse case in contact with it. We shall see anyway. A glance at the fitted pipe will show the area of concern (if it needs adjusting) , taking the engine mount off gives enough space to rectify any issues, no need to take inlet manifold off.
Good luck with yours too Jim, I know what you mean about the droplinks, same as the 406 ones I guess ? , they do have a hard time with the excess of speed humps we have nowadays
