Has anyone experienced this problem and would appreciate if you guys can help, its driving me insane.

That would be a missfire, and not at all related to the X-pipe. The only reason the check engine light ever flashes is when there is a missfire actively present.

Odds are you either have a coil going out, or need the plugs changed. BMW has always had some issues with coils which is why they use 2 different brands. If bosch coils act up too often, swap for bremi. And vise versa... which is why there were a few bulletins on them over the years.
