No you don't. I used a 14mm flex head ratcheting wrench. You can use another box wrench to get the torque to loosen it up. Penetrating oil of your preference will be your friend.

It depends on the way that you want to access the nut. From under the car, no, you don't need to remove the WGA. From under the hood, yes. Needle nose pliers will remove the pin that holds the WGA. Once removed you'll need a short socket extension for yer ratchet to work that bolt.
Under the car was impossible for me, under the hood was cake. PB Blaster!
Good luck!

You don't have to remove the waste gate actuator arm, but for me personally it made a world of difference. To take the actuator arm off you just need a ratchet and extension. Then just take a close-ended wrench and put it around the but and torque away. I have a 2014 GSR and it might be different for other years but this was hands down the easiest way to get to that nut, and I even had the car on a lift. I just couldn't get enough torque with a ratchet and swivel socket...just saying.

What did you have to use the lift for? I accessed all but one bolt from the top. The last bolt I accessed through passenger wheel well with an extension.

Great write up. Much better than some of the older ones I've seen. On a side note be advised the bolts on MY o2 housing heat shield were 12mm. Not 10mm, not sure if everyone's the same. Also know that if you remove the spring bolts and take the Downpipe portion off and then the o2 housing, you DO NOT have to take off the o2 housing heat shield. You just have to play with it, but it's really easy.
