Catalytic Converter
I recently purchased a 2004 F250 Superduty with the 6.0L Powerstroke Diesel engine. Anyhow, it has a Magnaflow 4" turbo back exhaust system on it with no catalytic converter that I can find. Did the 2004's come with catalytic converters? The truck was originally sold in what appears to be southern California and I purchased it in Las Vegas Nevada.
Unfortunately, the lame smog laws out here require diesel vehicles under 10,000 lbs. (gvwr) to get smogged checked at a ridiculous price (more than standard gas engines). The dealership I bought the truck from is trying to say that they didn't know it didn't have a catalytic converter on it. If it does need one to pass smog, they are willing to pay for it (because they have to by law anyhow). I really don't want to run a cat and was wondering if I can pass smog without one, or if I can make it removable. I'm hoping it didn't have one on it in the first place. Ford can't seem to tell me if it ever had a catalytic converter on it or not. The truck had a November 2003 build date if that might help.
Thanks!

Since the dealership is paying for it, I'm thinking about having it flanged so i can just take it back off. I think it is a worthless part and can't believe they even smog diesels out here. What do you guys think about running a high flow cat (perhaps one made by magnaflow) and removing the Magnaflow muffer. What will the difference be compared to having a hi-flow cat with no muffler vs. a muffler and not cat? (sound, performance, etc.)

I am thinking I will just bring it in for a smog and play stupid(cat? what cat? Diesel trucks have cats?....and then get argumentative since I didn't do the mods and the truck came from Cali (no smog for diesels there)

Where can I get the proper "cat delete pipe" for the 4" Magnaflow turbo back exhaust? Also, I think I'm going to use the Magnaflow universal cat instead of bothering with the stock cat since it is completely restrictive and really wont work unless they really f up my exhaust.

If they don't visually inspect the truck and ONLY smog it, the vehicle should pass with or without the cat if its in good running condition. With the VGT, EGR and 4 valves per cylinder (and reasonably decent calibration) the 6.0 just doesn't put out a hell of alot of particulate and NOx to begin with.
Gut the cat, cut 4 inch holes in the end, cut it in half, and weld it over the pipe that is there. That way it will pass visual inspection if they look, but it is only a hollow hull.
