I e had two AA x-pipes - one with HFCs and one with no cats/stock cats. I’ve had zero vibration issues with/without cats. Definitely no change in vibration with/without stock cats. I don’t have the forward must exhaust support (removed and misplaced when akra x-pipe was installed) and still no strange vibrations. Only issue I’ve encountered was the HFCs rubbing on speed bumps. Also, have an Akra HFC x-pipe and have had no vibration issues with it too.
