Do it. As long as you don't alter the OEM cats, you're good on your inspection. The same thing applies to warranty. They don't care what you do aft of the cats. While you're at it, lose the resonator too (replace it with an x-pipe).

There is one thing you should know, though. If you don't already hate AFM, you definitely will after the muffler delete. Unless you're prepared to tune it out (which is what many of us have done), you may not want a more aggressive exhaust. Tuning out the AFM can be grounds for denying your powertrain warranty.
