Thing is that i was rocking that setup before with no vibrations.
I took off the metal plate right in the middle of the Xpipe to see if it's related to it and I strongly believe it has to do with the exhaust. Once i took of the metal plate vibration for much worse and was in every gear. I didn't get a chance to put it back but i certainly will soon as i'm able to use the car again. The rubber mount looks fine but i'm considering buying new ones from BMW just to see if these have soften over time. My rear left rubber mount was ripped and it smothed out some of the vibration when i replaced it but not 100%.
At least now it's not any drivetrain part or anything.
