I want the Race, but if I do that, I need to know what to do when Smog rolls around. Do they even thoroughly look at the exhaust system?

As long as you don't mess w/ the converter, which you have a mani/cat. The manifold is also part of the converter. If you get the race exhaust later you might need a resonator or a muffler behind the flex aka Stealth muffler.
