If you are really looking into improving the performance you need to look at a few aspects...first of all with that lift you may want to look into regearing to a 4.56 or so, that will help. As far as CAI with exhaust the better the engine breathes the better it will work, when going with a CAI make sure it is a true one, dont go for anything that has an open filter as it will just suck in hot air, AFE and the TRD are almost identical, I would stay away from K&N and Injen. I would say work from the CAI down to headers, JBAs or Thorley, then if you really want to get into it lookin into a new y-pipe and possibly running new pipe to your exhaust, the trick with the muffler is that you want to make sure you still can maintain backpressure otherwise you will actually rob your engine of power, borla, gibson, Aero are some good ones. Aside from that there are engine upgrades that you could continue to do, but just remember when you start adding more power you need to strengthen everything else otherwise you will snap and break things.
