Increased vibration in cabin

To anyone who has done resonator deletes, including dinan midpipes or who has modified their exhaust, have you all noticed a little bit more vibrations inside the cabin? I did resonator deletes and there wasnt any vibrations in the first couple weeks and then i started noticing more vibrations in the steering wheel and just inside the cabin in general. Maybe the exhaist has “broken in” and is definitely louder and thats when i started noticing the increased vibrations. Vibrations increase with acceleration. Im trying to narrow this down because my car went for radiator replacement last week due to a leak and im trying to figure out if the vibrations are from the exhaust or from something that had come loose when the techs were working on my car. Thanks in advance!

Not with Dinan midPipe and free flow exhaust, running for about 10 months before I added downpipe, which brought the cabin noise up a tad. Should note that once I turned off the fake engine sounds, the cab got significantly quieter

I have a muffler delete and added a resonator- there’s a trim peice in the rear deck that vibrates an insane amount but other than that it’s fine

I have a Dinan res delete and a tuningwerk muffler. I get some vibrations at low rpms, but it's mild. Almost like a very low bass tone.

I have both the Dinan midpipe and rear section on my 240, and I have indeed noticed much more vibration. The rear deck behind the back seat headrests drive me crazy. It's the covers over the child safety harness strap, I'll put some tape or velcro in them because they buzz from both music and accelerations.

I have an M perf exhaust with Dinan midpipe and haven't noticed anytl additional vibration, just a lot more sound! . I would have whoever installed it check it out to make sure everything is right and nothing is touching or rubbing.
