Vibration accelerating hard from stop, muffler swaying.

Noticed a small vibration in steering wheel accelerating from a dead stop for a sec. It's the only vibration I have. Had a car follow me and they saw that my muffler was swinging from side to side on acceleration. The harder I accelerated the more violent the muffler moved.
Going to crawl underneath and see what's up. Need to know what to look for. Pics would be great if it's exhaust related cause I'm an exhaust noob.

Sounds like something supporting the exhaust system might have come loose or broken. I would just move the exhaust side-to-side with your hand to see what is allowing it to move like that. There are several exhaust system "hangers" that support the exhaust system, Just find them all & you'll probably find a problem with one of them.

If you find the problem & need someone else to fix it, take it to a small local muffler shop who will likely not rip you off or overcharge you. Chain shops like Midas, Meineke, etc. often (usually?) charge 2-3X what a small independent muffler shop charges for the same work.

I checked the hangars and they seem ok. Could it be anything else? It only does it on acceleration from a stop. It doesn't swing back and forth going over bumps.

Have you ruled out your transmission mount or motor mount(s)?

Check your u joints for the vibration. Exhaust hangars may be broke causing the exhaust to sway and if it has been recently lifted that will make the driveshaft shake when accelerating if the driveshaft is at a bad angle

As others said, Sounds like it could be the trans mount because the exhaust pipe is supported by the trans mount bracket.
