I'm getting close to just ripping out the entire system to replace it with stock. That's how much the vibration and drone is bothering me. You may soon see a post for anyone in south Florida that would like to do a swap for their OEM system. Or I guess the other option is to replace each piece unit the drone is gone. Which piece do I start with, I guess that goes back to the original question.
What piece is typically the least expensive to swap out? Maybe that how I decide.

If money is no concern, why not M Performance full system? Its BMW made so no issues will arise for sure.
