Car vibrates when downshifting?

Lately, I have been noticing when I downshift my car it vibrates?? the vibration is coming from below the counsel.

Does anyone have this problem? I have an a4 with slp headers. The vibration has caused one of the ypipe bolts to break on the passenger side. Any idea why this might happen?? And how it fix it??

Check your motor mounts and your trans mount. You may also have a broken exhaust hanger or bushing
