So have we verified if the mds just doesn’t work then?

that should be good for a 10-15lb payload increase :)

Nothing, just said it wasn't part of my build nor could they find a part # for it. So either supply chain issues, they aren't including them in our model moving forward or both. If you want to notice MDS just remove your mid-muffler like I did :D
Probably still won't hear it. I'm blasting my tunes most of the time.

I have a ‘22 2500 PW and it does not have the ATMM modules, just bundled wires with stubbed out wire connectors. I didn’t really notice a change at all when the MDS kicked on with the stock muffler. I changed out the stock muffler for the Mufflex with the Magnaglow and now I hear a slight tone difference and also feel a small difference in road/ride vibration. Nothing annoying and I probably would not have noticed any difference at all but I was looking for changes.

Maybe I shouldn’t have tossed the stock muffler, I may want it back on in 6 months but I doubt it.

Still enjoying my mid muffler delete and have gotten used to MDS kicking in which IMO sounds similar to an un-equal length header exhaust (ex Subaru 2.5L). Took a peak at a PW that hit the lot at my dealership and it didn't have the harmonics either.
