It does say 2wd & 4wd but there is no mention of 6.0L The specs are almost identical to the dynatech's minus haveing cats. I would guess that the headers would probably fit a 6.0L but the y-pipe might be different from looking at the Dyanatech website. I don't have any idea if that is correct or not tho.

I want some 1 7/8 inch primaries. 
If nothing else comes along soon ... I may have to try these out though, depending on how the flange holds up on the Pacesetters.

Question for yall, it says they fit 99-03. They will fit 99-07 trucks right? Dynatech's fitment is for 99-05. Is there any differance in fitment between the years?
