Texas F430 owners, please read

I'm looking at a F430 that hasn't had the exhaust manifold replacement done. It's a 2005 with 5k miles, and of course out of warranty. In California, a cracked F430 exhaust manifold would be covered for 7 years/70k miles due to their emissions law. Does anyone know if this is true of Texas?

Thanks!

 

Dang. I need to research this a bit, but do you know if this can be done by the dealer as a preemptive thing? I.e, I am looking at a Cali car right now that hasn't had the exhaust manifolds changed to the new design, and since the car is still registered in California, I am wondering if they can go ahead and perform the work now prior to a purchase and registration by myself.
