Headers!
So. Special tools. E10 external Torx socket, 12mm Allen key, lots of 14mm sockets and a 14mm open ended wrench.
By far and away the easiest header install I've ever done. Mainly due to the body lift. W/o the body lift this would have been damn near impossible and I would have given up a long time ago. All the factory studs came out nice and easy except for one. But it was a short stud and the nut came off clean. So I left it.
Pictures!
Here you can see the supplied plug for the EGR valve that required the 12mm Allen wrench.
Also fitted new PaceSetter cat'd mid pipes. Boltted right up w/ the appropriate gaskets, no leaks whatsoever.
In the last pic you can clearly see my aft passenger O2 sensor. Unfortunately, with the right angle CEL eliminators, this was the ONLY position it would work. So I ordered a straight one and that should be here this week so I can fix that.
Also, picked up some clevis shackles from Fastenal today. Unfortunately they are bright freaking yellow. I hate the color. Hate. So I'm repainting them blue to match the truck. More on that when the paint is dry.
