How will the OEM warranty be affected?
Yes it eliminates drone while keeping your stock mid pipe.

Dinan matches the BMW warranty on any product that is not marked "Race Purposes Only." So with this exhaust you would have the exact same BMW warranty and no BMW dealer would question it either because this is a Dinan product.

You shouldn't have a warranty issue with any axle back exhaust either but that all depends on each dealer since some are more forgiving than others but they all know that Dinan matches the BMW warranty so there would be no problems going with Dinan.
