Apologies for the late update but it took me this long to figure it out.
The rumbling noise I was getting was not normal, after the break in period it remained. After a ton of research I (and the wonderful people at Mod Auto) ran into a thread on e90post where someone had the same issue after installing the LSD. The issue for them was the driveshaft bearing housing got flipped upside down during install and got bolted up that way after the install. Apparently it still bolts up upside down but throws it off by a few millimeters, enough to cause this rumbling noise.
I took my car back to the shop, they flipped it around and now all noises have disappeared!
Hope this helps someone out in the future
