That has nothing to do with it bro. Unfortunately, EGR's have been a fact of life for gas engines, from the factory, regardless of being a California rig or not, for yeeeeeeeeeeeears.

Stewart, I am under the understanding that some of the Superduties and EX's (V-10's) had EGR's and some didn't. I don't know what determined which ones got them but I was told to check my exhaust manifold to see if the certain spot was solid and smooth or if it had the EGR in place when I bought my headers. No valve on mine.

Sooooooooo, if I posted bad info, I apologize. I was going by what I was taught at the tender age of 16.
Now that I've qualified the info in my post, I gotta say, "WTF?!?!"
I can't believe in this day and age of CAFE standards and CARB rules and regs that a modern gasoline powered engine was engineered without an EGR valve. THAT just blows my mind, and like the eternally hunted snipe, find difficult to believe exists!
Please, someone post up links.

Stewart, here is a photo clipped from ak-angler's Hedman Headers thread in the V-10 forum. His truck is a 2003 F-250 and you can see the round pad on the driver's side manifold where the EGR would be if it had one. Mine looks the same. This is my favorite picture that shows the factory Y-pipe, can't wait for my Hedmans to get here!

Clear as mud.........
I guess I mis-spoke (or miss-typed), the EGR if it's on a particular truck will have the EGR tube connected to the driver's side exhaust manifold. That tube then goes to the actual EGR. The EGR valve is not mounted to the exhaust manifold. All EGR's have to tap into the exhaust stream someplace to get the Exhaust Gases that they are Recirculating.
This thread got me to do some research on this topic. It seems that once Ford went to the better PI (Performance Improved) heads around model year 2000 or so the V-10's didn't need the EGR to pass most state emission standards. However some were still produced with the EGR, I'm not sure and I didn't find anything that really cleared it up but maybe it was just the Kalifornia trucks that kept them. Maybe Kali, NY and a few of the other states that bought into the whole CARB thing-a-ma-jig. Beats me, all I know is that my buggy aint got one!

With no provision for attaching the tube, that sucker didn't have an EGR.

Son of a Carmel-By-The-Sea BEACH, check this out.
I highlighted the part in red.
Damn I love FTE. Learning something new every day.
Thanks ford390gashog and Tom!
Reps to both.

Edit: Tom, I hit you, but 390gashog, I'm in rep jail since I hit you with reps already not too long ago.
SECTION 303-08: Engine Emission Control 2002 F-Super Duty 250-550/Excursion Workshop Manual
DESCRIPTION AND OPERATION Procedure revision date: 05/23/2001
--------------------------------------------------------------------------------
Engine Emission Control
CAUTION: Do not remove any part of the engine emission control system. Operating the engine without the engine emission control system will reduce fuel economy and engine ventilation. This will weaken engine performance and shorten engine life.
Some engines are equipped with an exhaust gas recirculation (EGR) system. The function of the EGR system is to reduce the emission of nitrogen oxide (NOx).
The engine emission control consists of the following components:
EGR valve
vacuum regulator solenoid
EGR tube
emission control vacuum harness
