LS6 manifold or LT's + ORY??
90% of LS6 intake manifolds do not have the provision (hole) for EGR, as they are mostly just taken off of some 01+ car. SLP sells an LS6 intake manifold WITH the hole, if you want to keep all your crap (california). My suggestion would be go and have all the emissions codes deleted so you don't have to run O2 sims in place of the rear O2 sensors. You will also be able to remove the EGR and AIR systems. I would go with the "race" version of the headers, as they have no provisions for EGR/AIR and would not make it obvious when someone looks under the hood and sees block off plates. Not that this would really matter i they look under the car and see 3" collectors

The 01+ cars don't have EGR because they use a slightly smaller camshaft with a bigger LSA, and diddn't need it per emissions requirements. It is the same camshaft used in the 6.0l truck motors from the time.

Search for some sponsers that are close to you and have ls1edit/hp tuners. They can delete the codes for AIR/EGR/rear O2's for usually less than the cost of O2 sensors alone!
I think Speed Engineering is in CA somewhere...
If you click alpha sponsor list at the top, you can enter your zipcode and find places close to you. OR you could ship your PCM somewhere and have it done if you don't live by anybody.
I'm not sure if you can do it or not in CA, but before you go and mod, get the car inspected so you'll be good for at least another year
