i'm partial to the Ram Air, especially since it's more direct on the Firebirds. the horsepower gain will be negligible, at best 2-4 HP.

the main thing you need to get rid of is the resonator, the large black plastic piece that sits behind your airbox. also, get a new airlid. Whisper Motorsports makes one specifically for the 3.8L V6's. this will help free up some more horsepower. after that, the next mod to do would be a full exhaust system - headers, hi-flow catalytic converter, and a cat-back exhaust system.
