California Emmisions Diffence Besides GPCM

[Doakster]

Does anyone now if there are any other differences between a California Emmisions 7.3 and a non Cali other than the use of the Glow plug control module. I live in Maine and you wouldn't think I have a 03' is a Cali truck, stumped me when I found out.

Cant be sure about Cali trucks at all but I just bought an 03, came out of New Jersey, and it has a cat on it, but thats just for the time being soon to be a kitty MIA

Does your cat have a typical O2 sensor installed in it? If so where are you going to install it once you get a new exhaust? Weld a bung onto you new exhaust?

I live in California and I have no cat on my '01, I read somewhere '02 was the first year of cats on Superduty Trucks.
