For the last couple of weeks I've been hearing a weird noise towards the rear end of my car when I accelerate, seems like it's worse when I'm going uphill, sounds like a box of shoes moving freely in the trunk of the car. At first I thought it was something in my the trunk but I have nothing loose, the spare wheel and all attachment are pretty well secure. The only thing that I can think of is that the dealership installed the F Sport exhaust to it, but not sure if that should be making that type of sound. Does anyone has/had this problem? Sound is pretty low but it still manages to upset me, specially since my car has less than 3k miles on it.

Try tugging on your exhaust left/right, forward/back when it's parked. Make sure it's not hot when you do! Your exhaust should have very little freedom to wiggle. It is bolted to the midpipe but muffler is suspended on hangers.

It is highly likely that at a certain RPM, your exhaust is hitting/vibrating off of something under the car. You can check yourself if you jack the rear end of the car up and check to see that there is clearance between the exhaust and all other parts of the underside of the car. My husband and I had to slightly adjust my ARK exhaust a couple of times after we installed it for clearance issues. It moves a lot when the car is the running. If you can't figure it out, take it back to the dealership for them to adjust it.
