throttle body = junk. dont waste your time. guys have over 800 hp with stock one. most people also have trouble with them and end up junking them.

coil packs = more for forced induction, correct. have not seen any N/A sheets that showed any gains.

cat back = waste of money

driveshaft = good gains. spydershaft is inexpensive and reliable.

Coil packs are only needed if you are having spark blowout issues, which can happen at higher boost levels. The only time I think that might happen NA is if you're running really high compression (12/1+) with way advanced timing (race fuel).
