This will all bolt up and should work but I recommend going either full Akra or Full Dinan. No sense in having half a Titanium system.
As far as Dinan vs Akra goes, the power gains are nearly identical and they are both virtually drone free systems with nice exhaust notes that are bearable on a daily driven car. Neither the Dinan or Akra will be better than the other as far as warranty is concerned.
I recommend going with the Akrapovic Evolution system and Dinan software to prevent the CEL. The Akrapovic Evolution system is actually used by BMW on their factory build GT4 cars. Maybe you should point this out to any dealer that wants to give you a hard time on warranty.
Check this out/show to your dealer:
