Anybody putting headers and true duals on a 3/4 ton soon?

From what I can tell by looking at my 1/2 ton and my neighbors 3/4 ton, the 3/4 ton exhaust pipes are significantly larger.

The manifolds are all the same. Yeah, I'm looking for the rest of the exhaust, the pipe/s that bolt from after the manifolds to the muffler.

No, the manifolds are not all the same. The drivers side manifold is the same on all the V8 trucks but there's a difference in the passenger side manifold (er it may be the other way around). I do know that on the 6.0L the collector is different on one side or the other. At any rate, if I were you I'd go with the OBX 6.0L setup and just put your own catback on. It'll be cheaper, sound nicer (doesn't have to be loud either) and be less stressful sourcing out all the parts.

Check out ebay. Installed a set of OBX style headers on my Denali and love them. $329 shipped to my door. They were for a 4.8/5.3 truck so the y had to be cut but they were about $200 less than one for a 6.0 truck. And the fit is excellant.

Sorry, no desire for headers. I do quite a bit of pheasant/grouse/duck hunting with the truck. Not going to sneak up on much with a loud truck.
