AA Tune, 3 stage manifold and Catless headers should get you to 275hp.
Skip the PBX you wont need it.
Skip the intake and either do the K&N on stock or something sealed. (BMW performance or the new AFE stage 2 intake)
I can't comment on the Dinan throttle body.
You wont gain any power from spark plugs. If your car isnt high mileage, dont mess with them.
Catless headers should be good for 15-20hp
Muffler wont gain much if any power. 2-5hp at best. Pick which ever makes the sound you like.
