Question after resonator delete/muffler vibration

Hi everyone, I have noticed a vibration from the mid pipe to the muffler after resonator delete. I am still new to the car so I'm not sure if this is normal. I don't think I noticed any vibrations prior to the resonator delete. Is this normal? Any help would be appreciated.

Btw, I am very content with the sound under load.

Thanks
Ryan

I have not noticed such. Did the shop undo any connectors or the crossbrace during he job that maybe isn't retightened all the way?

I'm not sure if the shop had to undo any connectors or crossbrace but I will start from there. Thanks for the suggestion.

make sure the heat shield and the pipe have Clearance too, my heat shield once was caught on my muffler giving it a rattle sound inside the cabin

I took the car back to the shop. They told me the vibration is from loss of backpressure from removing the resonator that it's 'normal'. No loose bolts or clearance issues.

The car seems to drive fine and I don't feel any vibrations in the car. Very strange. .I removed the resonator on my 6 series and no vibrations.

I didn't think the resonator really contributed all that much backpressure.

Does it visibly shake more than the rest of the car say if you peek under the car while idling? Is the vibration there under idle and under load too?

Did not notice any change in vibration at all on any changes I made to the resonator even when low in the rpm range

Looking at all the 'resonator delete' pictures on google images, I just realized my car does not have the secondary cats. Instead, they are straight pipes (no x/h pipe). I would think the dealer would have caught this and replace the mid pipe during the cpo process. In any event, could this be the reason why I'm experiencing the vibration (not having the secondary cats or x/pipe)?

Nevermind...2012's don't have secondary cats.
