I bought the OBX because they are stainless. I also wanted the fake cats, so I can pass a visual emissions inspection.

 

I almost bought them.... But installing those things is turning out to be like trying to pound a square peg in a round hole with a sledge........

 

I know all trucks are different but both headers went in from the bottom if i remember right and they were easier than the pacesetters. Getting the flanges lined up was kind of a pain. Then i had to find some plugs for the 02 bungs. But all aftermarket stuff is a little off so the problems we had were expected.

 

Like I said, ill pass. Im not caving in a primary even a little bit cuz its laying on my frame. Or mauling one to clear the front d-shaft.

 

I am worried about the tube size, it will do for a 6.0L but I would want bigger if I was going bigger ci at a later date.
99silver6.0 are you gonna sell them??

 

He doesn't have any OBX's to sell. He said he "almost bought some" but after hearing some of the issues with making them fit he didn't. I think he has some nice looking Thorley's that he needs to get installed.

 

Been done for a week!!!!

 

For a large CI engine I wouldnt buy any of the headers made right now, I would look at something custom with larger primaries and collectors. My OBX's have 1 3/4 primaries.

 

i believe I read somewhere that a set of kooks 1-7/8 f-body headers will work fine you just have to fab up a y-pipe

 

Yes. Guy that goes by QUIK did that with some stepped Kooks. I guess the pass side header collector kicks out to the right a bit. So all in all a new Y is all that would be needed.
