I bought a set of OBX stainless headers for my F150 extended cab 4.6 4 wheel drive. The guy I bought them from said he had them on an 03 Crew cab 4.6. Does anyone know if they switch exhaust in those years? My passenger side come almost straight out the rear of the headers, the OBX have more of an angle down. I would like to get them to fit but dont know where to start.

Thanks

There isn't any exhaust differences, only conflict would be 2wd headers and 4wd headers. 2wd ones are longer which make complicated fits in 4wd truck due to the transfer case.

 

Should be a pretty good fit, i believe the exhaust system is pretty much identical.

 

I just found out they did come off a 2 wheel drive so I guess that would be the differance, I did not ry the drivers side because the passenger was so out of line. I would post a picture but for some reason Im not allowed.

I just installed a set of OBX longtubes on my 2002 SCAB 4x4. The passenger header needed to be "modified" significantly to fit in the starter area. I also needed to weld on a different EGR fitting on the driver's side. Took a good amount of time but the result is excellent.
