Its super easy to pull off the bumper. On each side in the wheel well at the merge of the fender and the quarter panel there is a small torx screw. remove it and then under the car pop off the plastic body pins there is like 6 or so of them. open the hood and in the front there is a black plastic bit that pops out with a little force, its just held in place with more plastic clips on the bottom side of it. this will expose 2 bolts take them out. remove the front nose cone and disconnect the parking sensors. then just work your way around and pop off the bumper piece as one big unit. there is 1 cable that powers everything that connects under the frunk liner on the passenger side. If you have small enough hands you can get to it without pulling out the plastic frunk liner but your prob gonna have to pull it out, and that's it. super easy and like 10-15 min of work to get it off of there.
Curious, why are you removing it in the first place?
