Although my M3 has a sporadic front vibration so maybe I’m immune to it and it’s way less pronounced than that.

It's pretty subtle. Only happens when you really get into the throttle, between 3-4k RPM. It just feels like a big burly V8 doing it's thing. I only see it in 3-4 gear.

Well to be fair, it is a big burly V8. LOL

True haha. That's why it's so subtle! Definitely a little shutter at that range, but i don't find it terribly alarming.

3rd gear, 3000 rpm (50 mph), then accelerate progressively. See if you feel the same "rumble" for a few seconds like the rest of us...

Tried this in 3rd and 4th gear several times in my car. I feel zero abnormal vibrations-everything is smooth.

I have this issue but coincidentally I only started hearing the noise after about 4,000 miles. In addition after I shift into 6th my pipes shut completely off, as if you can't hear them. Also sometimes in 4th/5th the pipes go in and out. Dealership put a complete new exhaust system and noise got a little more quiet but the pipes still cut off in 6th. Any advice? Thanks

any fix to this? Anybody have any luck figuring it out? I'm really getting sick of the 3-4 gear vibration

Pull the fuse.
Even in track mode the NPP will shut at predetermined speeds.

Example, fifth gear at 40mph.
Above 40mph NPP is open and exhaust is loud, below 40mph the valves close and the exhaust is quiet, I guess to prevent low speed drone while in traffic.

Hmm I notice this as well. Anyone know the torque for the axle.nuts

I am not sure if I am hearing the same thing, my 2016 2SS automatic has been having a vibration and it seems when I accelerate after cruising for a few miles, almost feels like I am running over rumble strips that you see in the middle of the road. Not sure if this is the same thing? I only have about 5000 miles on the car.
