You can fix the midsection vibration by lowering the middle pipe away from the heat shields. You do this by loosening the front-middle and rear-middle hanger mounts, lowering the rear can a bit (this moves the midpipe down and away), then loosen the big pipe clamp at the rear-can and tip the tips back up where they belong. Then tighten the mid mounts. If you don't have the adjustable "2-piece L bracket" rear mid-mont just call AA and ask Andrew.
