Emissions LB7 Cali truck or not.
"There should be a large block of three digit codes in the glovebox. If one of them reads YF5 then it is CA emissions."
Ive searched and came up with this answer trying to find out how to tell if my truck has the Cali emissions. Its an 04 LB7. I have looked at the truck and the sticker is apparently missing from the truck. From what I have gathered from other post is if the truck has a vacuum pump it has the egr. The check engine lite has came on and im getting an EGR censor code. So i guess long story short it is safe to assume that my truck has the EGR?
Next question is can I block the EGR remove the vacuum pump and use a belt form a LLY. Sorry to sound like a dummy but I couldnt find any clear cut answers in searching.

I was wondering the same thing, I just installed a 5" straight pipe turbo back exhaust and my stock exhaust did not have a cat. I just had a muffler and i'm 100% sure it is a stock exhaust. When i take my truck to the CA inspection wouold they know that my truck did not come with a cat? sorry for being such a noob.

Is it possible for the truck to have a cat but no egr? I have a cat on my truck but the exhaust doesn't elbow it goes right to the turbo and I don't have a vacuum pump but I do have the three yf5 in my glove box
