Dunno bout 4x4. Call and ask for Joseph at DNA motoring.

 

I called and asked couple questions and they said 1 5/8 primaries and 2 1/2 collector and will fit 4x4

 

Lol, they are not 1 5/8, on this set. Mine were 2.5 collectors but 1 3/4 primaries. U can tell in the photos these are beefier than that.

 

My wife and Andrew are about to take some pics measuring the headers and upload them.

 

sounds good price is great the person I talked to prolly didnt know anything

 

 

Pics fail, I will do myself when I get home. Those pics look like 1 1/4 primaries and 2 inch y pipe. Lol.

 

do they have the wideband bung in the y pipe where the catback bolts on?The older style in the add you posted has it.

If these are 1 7/8" and 3",I might grab a set.How can you get that set if the add still has the old pic?

 

are you sure they are not 1 3/4 and 3" collector?

 

****. I meant 1 3/4. Sorry guys I was shopping headers for my car.
They ARE 1 3/4, as my truck headers were. The exhaust clamps they sent were 76 mm. I will double check everything when I get home.
