i know it may be a silly question...but what do they headers do exactly...and exhaust?

i know the CAI lets in Cold Air, and the engine can work better...

the exhaust creates a better noise...but can it increase performance?

i heard you have to get all 3 to make a difference.

I want to get the TRD CAI, and am looking for info
