That's basically correct. The flange connection for the mid-pipe necks down to fit the factory mid-pipes of the 5.0L, 5.4L, and 4.6L V8 trucks, which are all smaller than the 6.2L V8s. See this image here for reference. While I'm not certain if chopping off the resonator connection and welding it to the Outlaw kit would work, the Outlaw's inlet tubing is 3" in diameter after it necks up from the flange, and the Outlaw kit will require trimming to fit on wheelbases smaller than 163". It would be fairly trivial for a decent exhaust shop to trim the inlet tubing down to length by cutting off the flange, and then putting in one that would fit your 6.2L's mid-pipe.
