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.

What in your opinion is high mileage? I just hit 60k. I have an injen on the car right now but its causing a cel so I'm gonna take it off and put the eurobox w/ k&n in most likely. That seems to have the best reviews on this forum. I know exhaust doesn't really add a lot of hp. Do you think i can hit 275 if I leave the stock one in place?
