But it is the indirect "warranty" I'm concerned about. Apparently, BMW will not warrant engine failure if ECU modification is evident. I want DINAN to modify ECU with their software. I don't expect to have a warranty for the exhaust but engine should still be covered. NO?
Anyways if this is an ISSUE i will sell the x pipe from Akrapovic and run Dinan midpipe to Akra mufflers...
