Any mention of 2WD or 4WD? I dont see 6.0 mentioned but see no reason they wouldnt work. At least they are 1 3/4 Primaries.

 

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.

 

Here are some pics for all who don't want to go to ebay. I just swiped these from the auction I have not actually bought these....yet!

 

Correct- 6.0 does not Y together, but that is nothing that cant be altered for the price.

 

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.

 

It's hard to tell, but it looks like the EGR comes plugged off just like the Dynatech's do.

 

those look really nice..... i want !

 

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?
