A small ratchet wrench or a swivel socket and a extension. You don't have to take the bottom bolts all the way out either the y bridge has slots on the bottom side loosen them up a little and pull it out
X's 2 on the swivel and extension. Be carefull pulling the socket/swivel out though. I lost my socket in the valley when I pulled the tool out lol. I found it a while later when I pulled tue stock turbo.
