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:
the only reason why i thought about getting dinan xpipe was because of the warranty it possesses. But as a poster above clearly noted, dinan racing parts will affect bmw warranty.
i was afraid Akra delete-r would affect the ECU warranty or if something goes wrong with the engine...so what would make the dinan software different? since they state that it will affect your bmw standard warranty, then would it make getting the dinan software pointless?
