Ram 2500 acting like transmission issue or bad gas after muffler swap

2022 Ram 2500 Big Horn, just swapped out a straight through muffler for a quieter one (similar to a stock muffler) Now truck acts like it is stuttering when I step on it a little at certain speeds, similar to bad gas. All the shop did was cut out old muffler and put in new one. No engine lights on dash.

Are you sure your not hearing it drone due to the new muffler? what type of muffler did they use? does it have factory resonators? I would also scan it for codes or just take it back to whoever did the work.

There is really no drone, the muffler before had too much cabin drone. Not sure about resonators. Yes I am going to have dealer look at it since I have a couple recalls. Just don’t understand the hesitations
