Here's what we can do:
Ask the company who is going to do the ECU tune which sensors must be plugged in and which ones can be detatched.
If the ones that fit on our downpipe are enough it'll be possible to fit it.
Basically you need to know if they can make your car work as a EU spec 335d on the electronic side.
To solve the flange/pipe difference issue the only solution that comes to my mind is that you buy the front and centre pipes too.
You can purchase from Evolve, ask them a quote.
The parts you will need are:
046011 downpipe:

980242 front pipes

980213

You can fit them with the stock rear mufflers OR buy our racing mufflers too, with dual 90mm (046144 + 046124) or four exits (046106 + 046136).
